# CryptoBox -- FIPS 140-3 Level 3 Hardware Security Module

---

## 1. CryptoBox -- Hardware Security Module (FIPS 140-3 Level 3, Common Criteria EAL5+)

**CryptoBox is a portable hardware security module** -- a physically tamper-resistant cryptographic key storage device certified to the highest international security standards. FIPS 140-3 Level 3 and Common Criteria EAL5+ certified. This is not a software-based encryption solution. This is not a cloud key management service. This is hardware-rooted cryptographic sovereignty -- where keys are generated, stored, and processed within a dedicated tamper-resistant chip that cannot be read, copied, or extracted by any software, operating system, or adversary.

> CryptoBox cryptographic keys never leave the device. Even a compromised host computer cannot expose them. Every cryptographic operation -- signing, encryption, authentication, key generation -- occurs within the tamper-resistant hardware boundary of the CryptoBox itself. The host computer sends data for processing and receives the output, but never touches the key material. This architectural boundary is the fundamental difference between hardware-rooted security and software-based encryption.

CryptoBox is the hardware root of trust for the entire CryptoSuite ecosystem and anchors cryptographic security for CryptoRouter, CryptoChat, CryptoDrive, CryptoMail, CryptoPhone, and the S3-SENTINEL security platform. When CryptoBox is deployed, every cryptographic operation across the ecosystem inherits FIPS 140-3 Level 3 hardware security -- raising the entire security posture from software-grade to hardware-grade.

## 2. CryptoBox -- Executive Digest

CryptoBox is CryptoMize's portable hardware security module (HSM) -- the physical anchor of the CryptoSuite security ecosystem and the foundation of hardware-rooted cryptographic key sovereignty. Unlike software-based encryption solutions where keys reside in memory accessible to the operating system, CryptoBox stores and processes all cryptographic keys within a dedicated tamper-resistant hardware chip. Keys are generated, stored, and used exclusively within the device. They remain inaccessible to any software -- including the operating system of the host computer.

**Mission:** To provide sovereign cryptographic key protection through certified hardware security module technology that ensures private keys never leave physical control, even when connected to untrusted host systems.

**Core Purpose:** CryptoBox exists to solve the fundamental vulnerability of software-based encryption: the exposure of cryptographic keys to the operating system, applications, and potential malware. By moving all cryptographic operations into certified hardware, CryptoBox eliminates the primary attack vector against encrypted communications and data. The device ensures that even a fully compromised host -- infected with kernel-level rootkits, advanced persistent threats, or state-level malware -- cannot extract the cryptographic keys required to decrypt communications, forge signatures, or impersonate the user.

**The CryptoBox Advantage:** FIPS 140-3 Level 3 and Common Criteria EAL5+ represent the highest practical security certifications for portable hardware security modules. FIPS 140-3 Level 3 requires physical tamper resistance and tamper evidence with automatic key zeroization upon tamper detection -- meaning an attacker who gains physical possession of the device cannot extract keys through physical attacks. Common Criteria EAL5+ represents semiformally verified design and testing, providing assurance that the security architecture is correctly implemented and cannot be bypassed. Post-quantum cryptographic algorithms (CRYSTALS-Kyber-768 for key encapsulation, CRYSTALS-Dilithium3 for digital signatures) ensure the device remains secure against future quantum computing threats -- keys protected by CryptoBox today will remain secure tomorrow.

## 3. What CryptoBox Is -- Hardware Security Module Architecture

CryptoBox is a dedicated cryptographic processor designed to secure the cryptographic key lifecycle -- from generation through storage to usage and eventual destruction. It is the hardware root of trust for the entire CryptoSuite ecosystem. Every cryptographic operation across CryptoRouter, CryptoChat, CryptoDrive, CryptoMail, and CryptoPhone can optionally be anchored to CryptoBox, ensuring hardware-grade key protection at every layer.

**The Core Architecture:** CryptoBox contains a secure microcontroller with dedicated cryptographic accelerator hardware, tamper detection sensors, and physically shielded memory. The device generates cryptographic keys internally using a hardware random number generator (HRNG) with true entropy source derived from physical phenomena -- thermal noise, shot noise, or other quantum-level processes -- ensuring maximum cryptographic strength. Private keys are stored in encrypted form within battery-backed memory inside the tamper-resistant boundary. The secure microcontroller executes cryptographic operations using these keys but never exposes the raw key material to any external interface.

**Tamper Resistance:** FIPS 140-3 Level 3 certification requires physical tamper resistance and tamper evidence. CryptoBox's tamper-responsive design includes: zeroization circuitry that securely erases all key material upon tamper detection within microseconds, a tamper-evident physical enclosure with serialized anti-counterfeit seals that reveal unauthorized access attempts, environmental sensors monitoring temperature, voltage, and radiation to detect and respond to physical attacks, and active shielding that prevents micro-probing of internal circuits by detecting any attempt to penetrate the chip packaging.

**Post-Quantum Readiness:** CryptoBox integrates NIST-standardized post-quantum cryptographic algorithms (standardized August 2024): CRYSTALS-Kyber-768 for key encapsulation mechanism (KEM) and CRYSTALS-Dilithium3 for digital signatures. These algorithms are based on the hardness of lattice problems -- mathematical problems intractable for both classical and quantum computers. This ensures that cryptographic material protected by CryptoBox remains secure against future cryptographically-relevant quantum computers capable of breaking RSA and ECC through Shor's algorithm.

**Cross-Platform Compatibility:** CryptoBox operates across all major operating systems and platforms through standardized cryptographic interfaces including PKCS#11 v2.40/v3.0 for cross-platform cryptographic token interface, Microsoft CNG/KSP for Windows native cryptographic integration, Java JCA/JCE for enterprise Java applications, and OpenSSL engine integration for Linux-based infrastructure. Integration with applications, protocols, and services is transparent -- applications interact with CryptoBox through standard cryptographic APIs without modification, making hardware-grade security accessible without custom development.

## 4. The CryptoBox Imperative -- Why Hardware Security Modules Are Essential

Software-based encryption is mathematically sound but operationally vulnerable. The cryptographic algorithms themselves -- AES, ChaCha20, ECDSA, Ed25519 -- are robust against computational attack when correctly implemented. But the environment in which they execute -- the operating system, applications, memory, and storage of a general-purpose computer -- introduces attack surfaces that sophisticated adversaries can exploit with devastating effectiveness.

**The Key Exposure Problem:** When cryptographic keys are stored in software, they exist in memory accessible to the operating system. Malware, rootkits, and even legitimate applications with sufficient privileges can read key material from memory through techniques including process memory dumping, cold boot attacks on RAM, DMA attacks via Thunderbolt/PCIe, and kernel-level keyloggers. A computer compromised at the operating system level cannot be trusted to protect its own keys. The fundamental principle of trusted computing holds that a system cannot protect secrets from an adversary who has achieved the same privilege level as the system itself.

**The Supply Chain Vulnerability:** Cloud-based key management services (AWS KMS, Azure Key Vault, GCP Cloud KMS) require trust in the cloud provider's infrastructure, personnel, and security posture. Keys managed in the cloud are accessible to the provider's systems and personnel -- a trust requirement that sovereign entities cannot accept. Even with customer-managed keys (CMK) and hardware security modules on the provider side, the architecture introduces dependencies on provider infrastructure, legal compliance with provider jurisdiction (including potential data access demands under laws such as the US CLOUD Act), and exposure to provider-side insider threats.

**The Physical Security Gap:** Portable devices containing encrypted data can be lost or stolen. Without hardware security modules, the security of encrypted data depends entirely on the strength of the passphrase protecting the device key -- which can be attacked through brute force, social engineering, or forensic analysis. Hardware security modules raise the barrier by requiring both physical possession of the device and authorized credentials, with tamper-responsive mechanisms that destroy key material if physical attack is detected.

**The Future Threat of Quantum Computing:** Public-key cryptography algorithms widely deployed today (RSA-2048, ECDH P-256, ECDSA P-384) are mathematically vulnerable to cryptographically-relevant quantum computers through Shor's algorithm. Although large-scale fault-tolerant quantum computers do not yet exist, intelligence agencies and security-conscious organizations operate under the assumption that encrypted communications recorded today may be decryptable when such computers become available -- the "harvest now, decrypt later" threat model. Hardware security modules deployed today must be capable of post-quantum cryptographic operations to protect long-term secrets. NIST-standardized post-quantum algorithms (CRYSTALS-Kyber-768, CRYSTALS-Dilithium3) provide defense against this emerging threat vector, and CryptoBox integrates these algorithms natively.

CryptoBox addresses every dimension of these challenges through certified hardware architecture that ensures keys remain under exclusive physical control.

## 6. Cryptographic Key Lifecycle Management

CryptoBox manages the complete cryptographic key lifecycle from entropy generation through secure destruction, ensuring that keys are protected at every stage. The lifecycle is entirely contained within the tamper-resistant hardware boundary -- keys never exist in software-accessible form at any point.

**Key Generation:** All cryptographic keys are generated within the CryptoBox secure microcontroller using the integrated hardware random number generator (HRNG). The HRNG derives entropy from physical quantum-level processes -- thermal noise across semiconductor junctions -- producing true random numbers that pass NIST SP 800-90B health tests and entropy source validation. Keys generated within CryptoBox never exist in plaintext outside the tamper-resistant boundary at any point in their lifecycle. The generation process includes extraction from the entropy source, entropy conditioning through cryptographic mixing, post-processing validation against statistical randomness tests, and secure storage within the tamper-resistant memory.

**Key Storage:** Private and secret keys are stored in encrypted form within dedicated battery-backed memory (BBRAM) inside the secure microcontroller. The memory is protected by active mesh shielding that detects any attempt to probe the chip packaging, environmental sensors that trigger zeroization if physical attack parameters are detected, and encrypted storage where keys are encrypted under a device-specific key encryption key (KEK) derived from the PUF (Physically Unclonable Function) of the secure element. This layered protection ensures that even sophisticated physical attacks cannot extract key material.

**Key Usage:** All cryptographic operations using stored keys execute within the CryptoBox hardware. The host computer sends data to CryptoBox and receives the output, but never has access to the key material. Operations supported include RSA encryption/decryption, ECDSA/Ed25519/Dilithium3 signature generation and verification, symmetric encryption/decryption (AES-256-GCM, ChaCha20-Poly1305), key agreement (ECDH, X25519, Kyber-768 KEM), hash computation (SHA-256/384/512, SHA-3), and HMAC generation and verification.

**Key Backup and Escrow:** Enterprise deployments support secure key backup and escrow through Shamir's Secret Sharing (threshold cryptography). Cryptographic keys can be split into shards distributed among trusted parties using an m-of-n threshold scheme (e.g., 3-of-5, 5-of-7). The key can only be reconstructed when the required threshold of shards is presented. This architecture ensures that no single individual or compromised system can recover backed-up keys. Backup shards are individually encrypted and can be stored separately for maximum security.

**Key Rotation:** CryptoBox supports cryptographic key rotation -- generating new key pairs while maintaining the ability to decrypt previously encrypted data with archived keys. Rotation policies are configurable per key type and use case. Key rotation can be triggered automatically based on crypto-period expiration, on demand by authorized administrators during compromise response, or based on compliance schedule (e.g., annual rotation for CA keys).

**Key Destruction:** When keys are rotated, decommissioned, or when tampering is detected, CryptoBox executes cryptographic key destruction through secure zeroization of the memory cells containing key material. The zeroization process overwrites key memory with multiple patterns (ones, zeros, random data) within microseconds, ensuring that residual data cannot be recovered through forensic memory analysis. Zeroization is automatic upon tamper detection and can be triggered manually by authorized administrators.

## 7. Core Capabilities -- What CryptoBox Does

**What is CryptoBox?** CryptoBox is a portable hardware security module that generates, stores, and processes cryptographic keys within a certified tamper-resistant hardware boundary. Keys never leave the device. Even a compromised host computer cannot extract them. Every cryptographic operation executes within the hardware boundary, ensuring that key material is never exposed to the host operating system, applications, or network.

**The Seven Core Capabilities:**

**1. Secure Key Generation** -- Cryptographic keys are generated within the CryptoBox hardware using a NIST SP 800-90B compliant hardware random number generator. Keys never exist in software-accessible memory at any point in their lifecycle. True entropy from physical quantum-level sources ensures maximum cryptographic strength. The generation process supports asymmetric key pairs (RSA, ECC, post-quantum), symmetric keys (AES, ChaCha20), and secret sharing shards for enterprise escrow deployments.

**2. Tamper-Protected Key Storage** -- Private keys are stored in encrypted form within the tamper-resistant boundary of the CryptoBox secure microcontroller. Battery-backed memory preserves keys when the device is disconnected. Automatic zeroization erases all keys upon tamper detection within microseconds. Encrypted storage under a device-unique wrapping key ensures that even extracted memory content would be indecipherable.

**3. Hardware Cryptographic Operations** -- All cryptographic operations -- encryption, decryption, signing, signature verification, key agreement -- execute within the CryptoBox hardware. The host computer sends data to CryptoBox and receives output, but never has access to key material. This architecture ensures that even a compromised host cannot perform unauthorized cryptographic operations without the physical CryptoBox device, providing both key security and access control.

**4. Multi-Algorithm Support** -- CryptoBox supports the full spectrum of modern cryptographic algorithms: AES-256-GCM, AES-256-CBC, ChaCha20-Poly1305 for symmetric encryption; RSA-4096, ECC (P-256, P-384, P-521, Curve25519) for asymmetric operations; CRYSTALS-Kyber-768 for post-quantum key encapsulation; CRYSTALS-Dilithium3 for post-quantum digital signatures; ECDSA, Ed25519 for classical digital signatures; ECDH, X25519 for classical key agreement; SHA-2 and SHA-3 for hash operations. This comprehensive algorithm support ensures compatibility with existing PKI infrastructure while enabling post-quantum readiness.

**5. Hardware Authentication** -- CryptoBox can serve as a hardware authentication device for VPN access, server authentication, document signing, encrypted email, and secure web authentication via FIDO2/WebAuthn. Hardware-rooted authentication eliminates password-based vulnerabilities and phishing risks. Multi-factor authentication combines possession of the CryptoBox device with knowledge of a PIN or biometric verification.

**6. Key Escrow & Recovery** -- Enterprise deployments support cryptographically secure key escrow and recovery through Shamir's Secret Sharing. Cryptographic keys can be split into threshold-configurable shards (e.g., 3-of-5, 5-of-7) distributed among trusted parties. Key material is reconstructed only within the CryptoBox hardware when the required threshold is met. This architecture provides business continuity while preventing any single party from accessing keys unilaterally.

**7. Cross-Platform Integration** -- CryptoBox integrates with applications through standard cryptographic interfaces: PKCS#11 v2.40/v3.0 for cross-platform token access, Microsoft CNG/KSP for Windows-native integration, Java JCA/JCE for enterprise Java environments, OpenSSL engine for Linux infrastructure, and FIDO2/WebAuthn for web authentication. Integration is transparent -- existing applications work with CryptoBox through standard APIs without code modification.

## 8. Physical Security & Tamper Response Architecture

CryptoBox's physical security architecture is designed to defeat the most sophisticated hardware attack techniques -- from simple probing through advanced semiconductor analysis. The architecture implements multiple layers of defense that collectively meet FIPS 140-3 Level 3 and Common Criteria EAL5+ requirements.

**Tamper Detection Sensors:** CryptoBox incorporates multiple environmental sensor types that continuously monitor for physical attack indicators. Temperature sensors detect deviations beyond normal operating range (-20°C to +65°C) that may indicate freeze spray attacks or thermal manipulation. Voltage sensors detect power supply glitching and overvoltage/undervoltage conditions characteristic of fault injection attacks. Radiation sensors detect exposure to ionizing radiation that might be used to induce bit flips in secure memory. Light sensors detect decapsulation attempts where the chip packaging is removed.

**Active Shielding:** The secure microcontroller die is protected by an active shield mesh -- a conductive layer with continuously monitored electrical properties. Any attempt to penetrate the shield (through focused ion beam milling, laser ablation, or mechanical probing) disrupts the electrical characteristics, which is immediately detected. The shield topology is randomized per-device, ensuring that knowledge of one device does not enable bypass of another.

**Zeroization Circuitry:** Upon detection of any tamper event, CryptoBox executes automatic key zeroization within microseconds. Dedicated zeroization circuits -- independent of the main processor -- trigger immediate discharge of the battery-backed memory capacitors and overwrite all key storage cells with multiple patterns. The zeroization circuit is powered by a dedicated capacitor that provides sufficient energy to complete erasure even if main power is interrupted during the attack.

**Tamper-Evident Enclosure:** The physical enclosure of CryptoBox reveals any unauthorized access attempt. Tamper-evident seals with serialized holographic elements provide visual evidence of tampering. The enclosure is bonded to the circuit board in a way that makes non-destructive opening impossible -- any attempt to open the enclosure permanently damages the device.

**Tamper Response Policy:** The tamper response is configurable per deployment requirements. Standard response includes immediate zeroization of all key material, permanent device lockout preventing further use, and audit log generation recording the tamper event timestamp and sensor trigger source. Enterprise deployments can configure additional responses including remote alerting and automatic key revocation.

## 9. Advanced Cryptographic Capabilities

Beyond core key management and cryptographic operations, CryptoBox delivers advanced capabilities that address the most demanding security requirements of sovereign and institutional clients.

**Multi-Party Computation (MPC) Support:** CryptoBox provides hardware-rooted cryptographic foundations for multi-party computation protocols. Threshold signing operations split across multiple CryptoBox devices enable distributed authorization architectures where no single device can complete a cryptographic operation independently. This capability is essential for high-value transaction authorization, blockchain validator key management, and command-and-control authentication for sensitive infrastructure.

**Hardware-Backed Attribute-Based Encryption (ABE):** CryptoBox supports attribute-based encryption schemes where decryption is possible only when the requesting party possesses a specific set of cryptographic attributes. This enables fine-grained access control policies enforced at the hardware level -- file-level access policies, time-based decryption windows, and geo-fenced cryptographic operations where key usage is restricted by device presence requirements.

**Quantum-Safe Hybrid Operations:** CryptoBox operates in hybrid mode, executing both classical and post-quantum cryptographic algorithms in parallel for transitional deployments. Organizations migrating from ECC/RSA to NIST-standardized post-quantum algorithms can deploy CryptoBox in hybrid configuration where every cryptographic operation is simultaneously secured by both algorithm families. This eliminates the quantum transition risk window -- security is never weaker than the stronger of the two algorithm families at any point.

**Hardware Security Module Clustering:** Enterprise deployments support CryptoBox clustering where multiple devices operate as a unified cryptographic resource pool. Keys can be distributed across cluster members using threshold cryptography, ensuring availability even if individual devices are offline. Load balancing across cluster members enables throughput scaling for high-volume cryptographic operations. The specific clustering protocols and synchronization mechanisms are architecture-level details reserved for qualified engagements.

**Secure Enclave Integration:** CryptoBox provides cryptographic anchoring for secure enclave technologies (Intel SGX, AMD SEV, ARM TrustZone). The hardware root of trust extends into trusted execution environments, enabling workload attestation and cryptographic verification of enclave integrity. This integration layer enables confidential computing architectures where data processing occurs in attested hardware environments with hardware-rooted cryptographic verification.

## 11. Benefits & Value -- What CryptoBox Delivers

**Absolute Key Sovereignty:** Keys that cannot be extracted, copied, or accessed by any software or operating system. The physical possession of the CryptoBox device combined with authorized credentials is the sole requirement for authorized cryptographic operations. No cloud provider, no third party, and no software process can access keys protected by CryptoBox.

**Certified Security:** FIPS 140-3 Level 3 and Common Criteria EAL5+ certifications represent measurable, internationally recognized security assurance verified through independent laboratory evaluation. These certifications require that the security architecture withstands rigorous testing -- they are not self-attested claims but verified outcomes.

**Post-Quantum Readiness:** Integrated CRYSTALS-Kyber-768 and CRYSTALS-Dilithium3 ensure cryptographic operations remain secure against future quantum computing threats. Keys protected by CryptoBox today will remain secure tomorrow. The "harvest now, decrypt later" threat model is neutralized by post-quantum cryptographic algorithms that resist attack by both classical and quantum computers.

**Operational Simplicity:** Standardized cryptographic interfaces (PKCS#11, CNG, JCA/JCE, OpenSSL) enable transparent integration with existing applications and workflows. Hardware security without operational complexity. Applications interact with CryptoBox through the same cryptographic APIs they already use -- no code changes required.

**Zero Software Key Exposure:** By ensuring cryptographic keys never enter the host computer's memory, CryptoBox eliminates the most common attack vector against encrypted communications and data. Even a host compromised by advanced persistent threats cannot expose keys that the architecture prevents it from accessing.

**Tamper-Proof Physical Security:** Physical possession of the device is insufficient to extract keys. Tamper-responsive zeroization ensures that any physical attack attempt destroys key material before extraction is possible. The device provides both logical and physical security in a single portable form factor.

## 13. Enterprise PKI & Certificate Authority Integration

CryptoBox serves as the hardware root of trust for enterprise public key infrastructure (PKI), providing FIPS 140-3 Level 3 certified protection for certificate authority (CA) private keys. In enterprise PKI deployments, the security of the entire certificate ecosystem depends on the protection of the root CA key -- if this key is compromised, every certificate issued under that CA is untrustworthy.

**Root CA Key Protection:** CryptoBox generates and stores the root CA private key within the tamper-resistant hardware. The root key never exists in software-accessible form at any point in its lifecycle. All certificate signing operations are performed within CryptoBox -- the CA software sends certificate signing requests (CSRs) to CryptoBox and receives signed certificates, but never has access to the CA private key.

**Subordinate CA and Issuing CA Keys:** CryptoBox supports multiple key containers for tiered PKI architectures. Root CA keys, subordinate CA keys, and issuing CA keys can each be stored on separate CryptoBox devices for physical separation of duties. This enables compliance with PKI best practices requiring offline root CAs and physically secure issuing environments.

**Code Signing Infrastructure:** Organizations deploying code signing use CryptoBox to protect code signing private keys. Integration with CI/CD pipelines enables automated code signing where the build server requests signature operations from CryptoBox without ever accessing the private key.

## 17. The 5W1H Deep Dive

**What is CryptoBox?**
CryptoBox is a FIPS 140-3 Level 3 and Common Criteria EAL5+ certified portable hardware security module that generates, stores, and processes cryptographic keys within a tamper-resistant hardware boundary where keys never leave the device. It anchors the hardware root of trust for the entire CryptoSuite ecosystem.

**How does CryptoBox protect cryptographic keys?**
Keys are generated internally using a NIST-compliant hardware random number generator with quantum entropy source, stored in encrypted form within the tamper-resistant secure microcontroller with active shielding and environmental sensors, and automatically erased upon tamper detection through zeroization circuitry that operates within microseconds.

**Why is hardware-based key protection necessary?**
Software-based encryption exposes keys to the operating system, applications, and potential malware on the host computer. A compromised operating system can read key material from memory through multiple attack vectors. Hardware security modules eliminate this exposure by ensuring keys never enter software-accessible memory -- cryptographic operations execute within the hardware, and the host only receives the output.

**When should an organization deploy CryptoBox?**
When cryptographic keys must be protected against advanced adversaries with software exploitation capabilities, when FIPS certification is a compliance requirement for government or regulated industry procurement, when post-quantum readiness is required for long-term secrets that must remain secure beyond the arrival of cryptographically-relevant quantum computers, or when cloud-based key management is unacceptable for sovereignty or legal jurisdictional reasons.

**Who uses CryptoBox?**
Government agencies, defense establishments, enterprise security teams, legal professionals, financial institutions, blockchain custodians, healthcare organizations, and individuals requiring the highest standard of hardware cryptographic key protection. Deployed across government, defense, enterprise, and individual use cases in 18 countries.

**Where does CryptoBox operate?**
As a portable USB-connected HSM across all major operating systems (Windows, macOS, Linux); as an embedded module in CryptoRouter, CryptoPhone, and S3-SENTINEL deployments; across air-gapped, cloud, and hybrid deployment environments; in enterprise, government, and individual use cases across 18 countries.

## 19. PAA-Optimized FAQ -- CryptoBox

**What is a hardware security module?**
A hardware security module (HSM) is a dedicated cryptographic processor that generates, stores, and processes cryptographic keys within a tamper-resistant hardware boundary. CryptoBox achieves FIPS 140-3 Level 3 and Common Criteria EAL5+ certification for portable HSM operation.

**What is FIPS 140-3 Level 3 certification?**
FIPS 140-3 Level 3 requires physical tamper resistance and tamper evidence, including tamper-responsive zeroization that erases all keys upon detection of physical attack. CryptoBox holds this certification for its portable form factor. Level 3 also requires identity-based authentication, physical or logical separation of interfaces, and a trusted path for authentication data entry.

**What post-quantum algorithms does CryptoBox support?**
CryptoBox integrates CRYSTALS-Kyber-768 for key encapsulation and CRYSTALS-Dilithium3 for digital signatures, both NIST-standardized post-quantum cryptographic algorithms (standardized August 2024) that are resistant to attacks by both classical and quantum computers. These algorithms are based on the hardness of lattice problems.

**How does CryptoBox prevent key extraction?**
Keys are generated, stored, and used exclusively within the CryptoBox tamper-resistant hardware. The host computer sends data for cryptographic processing and receives output, but never has access to key material. Tamper detection through environmental sensors and active shielding triggers automatic key zeroization within microseconds.

**Can CryptoBox integrate with existing applications?**
Yes, through standardized cryptographic interfaces including PKCS#11 v2.40/v3.0 (cross-platform), Microsoft CNG/KSP (Windows), Java JCA/JCE (enterprise Java), OpenSSL engine (Linux/Unix), and FIDO2/WebAuthn (web authentication). Applications interact with CryptoBox through standard APIs without modification.

**What is the difference between CryptoBox and software encryption?**
Software encryption stores keys in host computer memory accessible to the OS and applications. CryptoBox keeps keys within tamper-resistant hardware where even a fully compromised host computer cannot extract them. Software encryption security depends on the OS security posture; CryptoBox security is architecture-enforced and independent of the host.

**Is CryptoBox portable?**
Yes, CryptoBox is available in a portable USB key form factor (85mm x 25mm x 10mm, 18 grams) for individual use and as an embedded module (25mm x 15mm x 5mm) for integration into CryptoRouter, CryptoPhone, and enterprise infrastructure deployments.

**What is Common Criteria EAL5+ certification?**
Common Criteria EAL5+ (Evaluation Assurance Level 5+) is an international standard (ISO 15408) for computer security certification, representing semiformally verified design and testing with systematic vulnerability analysis. CryptoBox holds EAL5+ certification for its hardware security module implementation. EAL5+ is the highest evaluation assurance level commonly required for government and defense procurement.

**Does CryptoBox require internet access?**
No. CryptoBox operates entirely as a locally connected USB device with no network connectivity requirement. It is fully functional in air-gapped environments where no internet access is available. Firmware updates can be performed via signed update packages transferred through the USB connection.

**What operating systems does CryptoBox support?**
CryptoBox supports Windows (7, 10, 11, Server 2016+), macOS (10.15+), Linux (all major distributions including Ubuntu, RHEL, Debian, Arch), and Android (via USB OTG). iOS support is available for specific CryptoBox-enabled applications.

**How many keys can CryptoBox store?**
CryptoBox supports hundreds of independent key containers with no practical limit for typical use cases. Key storage capacity varies by key type -- approximately 512 RSA-4096 key pairs or 1,024 ECC key pairs. The embedded module variant supports configuration-specific capacity.

**Can CryptoBox keys be backed up?**
Yes. Enterprise deployments support cryptographically secure key backup through Shamir's Secret Sharing with configurable threshold schemes (m-of-n). Backup shards are individually encrypted and can be stored separately. Key recovery requires the configured threshold of shards and occurs within the CryptoBox hardware.
