Post-Quantum Encryption
Overview
Post-Quantum Encryption is a vanguard of quantum-proof security, arming UnoLock with advanced cryptographic defenses to shield your data, identity, and digital assets against future quantum computing threats. Integrated across all tiers, Free, Inheritance, Sovereign, and HighRisk, this feature employs lattice-based algorithms like Kyber and Dilithium, alongside AES-256 GCM, to ensure your vault remains an impregnable fortress for decades. UnoLock’s forward-thinking encryption delivers unmatched protection, securing your digital sovereignty today and tomorrow.
How It Works
- Post-Quantum Key Exchange: UnoLock uses Kyber-based Key Encapsulation Mechanism (KEM) to negotiate secure session keys for API communication, replacing vulnerable elliptic curve methods with quantum-resistant cryptography.
- Quantum-Safe Authentication: API servers authenticate with Dilithium digital signatures, ensuring clients connect only to legitimate UnoLock backends, immune to quantum-powered Man-in-the-Middle attacks.
- Client Data Master Key Protection: The Client Data Master Key (CDMK) is generated and wrapped using a FIDO2 WebAuthn authenticator, safeguarded on-device with quantum-resistant encryption and biometric verification.
- End-to-End Data Encryption: All user data, files, archives, and metadata, is encrypted client-side with AES-256 GCM, maintaining a 128-bit security margin against quantum attacks like Grover’s algorithm.
- Dual-Layer Cloud Storage: Data is encrypted client-side with AES-256 before cloud storage, supplemented by AWS S3 server-side encryption, ensuring quantum-safe protection at rest.
Security Implications
- Quantum-Resistant Defense: Kyber and Dilithium algorithms protect against quantum attacks (e.g., Shor’s algorithm), ensuring your data remains secure as quantum computing advances.
- Forward Secrecy: Per-session key negotiation and re-keying prevent retroactive decryption, safeguarding past communications even if future keys are compromised.
- Zero-Knowledge Privacy: Client-side key management and stateless servers ensure UnoLock cannot access your data, maintaining privacy against both classical and quantum threats.
Use Cases
- Long-Term Data Protection: Individuals can secure sensitive files (e.g., legal documents, crypto keys) with confidence that they’ll remain safe against future quantum decryption.
- Corporate Data Security: Businesses can protect proprietary information or client data, ensuring compliance and security in a quantum future.
- High-Risk Asset Management: Cryptocurrency investors can safeguard wallet seeds or financial records, leveraging quantum-hardened encryption for enduring protection.
Why It Matters
Post-Quantum Encryption fortifies UnoLock with a shield against the quantum future, ensuring your digital assets and privacy endure beyond today’s threats. This feature delivers peace of mind, securing your vault with cryptography that outpaces the evolution of computing itself.
