DOCUMENT SECTIONS

SYSTEM OVERVIEW

THE Q0 QUANTUM-RESISTANT SECURITY PLATFORM PROVIDES A COMPREHENSIVE SUITE OF CRYPTOGRAPHIC PRIMITIVES AND PROTOCOLS DESIGNED TO WITHSTAND ATTACKS FROM BOTH CLASSICAL AND QUANTUM COMPUTERS. THE SYSTEM IMPLEMENTS NIST POST-QUANTUM CRYPTOGRAPHY STANDARDS WITH ADDITIONAL SECURITY HARDENING.

THIS DOCUMENTATION PROVIDES TECHNICAL SPECIFICATIONS FOR IMPLEMENTATION AND INTEGRATION WITH EXISTING SYSTEMS. ALL COMPONENTS HAVE BEEN RIGOROUSLY TESTED AGAINST SIMULATED QUANTUM ATTACKS.

CRYPTOGRAPHIC ALGORITHMS

Q0 IMPLEMENTS THE FOLLOWING POST-QUANTUM CRYPTOGRAPHIC ALGORITHMS, SELECTED FOR THEIR SECURITY AGAINST BOTH CLASSICAL AND QUANTUM ATTACKS, PERFORMANCE CHARACTERISTICS, AND IMPLEMENTATION VIABILITY.

KEY EXCHANGE MECHANISMS

THE PRIMARY KEY EXCHANGE MECHANISM IS BASED ON CRYSTALS-KYBER, A LATTICE-BASED KEY ENCAPSULATION MECHANISM SELECTED BY NIST FOR STANDARDIZATION. Q0 IMPLEMENTS KYBER-1024 FOR MAXIMUM SECURITY.

KYBER PARAMETERS
KYBER-1024 { SECURITY_LEVEL: 5, // AES-256 equivalent PUBLIC_KEY_SIZE: 1568 bytes, PRIVATE_KEY_SIZE: 3168 bytes, CIPHERTEXT_SIZE: 1568 bytes, SHARED_SECRET_SIZE: 32 bytes }

DIGITAL SIGNATURES

DIGITAL SIGNATURES ARE IMPLEMENTED USING CRYSTALS-DILITHIUM, A LATTICE-BASED SIGNATURE SCHEME SELECTED BY NIST FOR STANDARDIZATION. Q0 IMPLEMENTS DILITHIUM-5 FOR MAXIMUM SECURITY.

DILITHIUM PARAMETERS
DILITHIUM-5 { SECURITY_LEVEL: 5, // AES-256 equivalent PUBLIC_KEY_SIZE: 2592 bytes, PRIVATE_KEY_SIZE: 4864 bytes, SIGNATURE_SIZE: 4595 bytes }

SYMMETRIC ENCRYPTION

THE SYSTEM USES AES-256 IN GCM MODE FOR SYMMETRIC ENCRYPTION. WHILE AES-256 IS VULNERABLE TO GROVER'S ALGORITHM, IT PROVIDES ACCEPTABLE SECURITY IN THE POST-QUANTUM ERA BY DOUBLING THE EFFECTIVE KEY SIZE.

AES PARAMETERS
AES-256-GCM { KEY_SIZE: 32 bytes, NONCE_SIZE: 12 bytes, TAG_SIZE: 16 bytes, QUANTUM_SECURITY: 128 bits // Against Grover's algorithm }

IMPLEMENTATION GUIDELINES

THIS SECTION PROVIDES IMPLEMENTATION DETAILS FOR INTEGRATING Q0 SECURITY INTO EXISTING SYSTEMS. THE API FOLLOWS A MODULAR DESIGN FOR FLEXIBLE DEPLOYMENT OPTIONS.

INTEGRATION EXAMPLE
// Initialize the Q0 security subsystem const q0 = new Q0SecurityProvider({ keyExchange: 'KYBER-1024', signatures: 'DILITHIUM-5', symmetricEncryption: 'AES-256-GCM', hashFunction: 'SHA3-256' }); // Generate key pair const keyPair = await q0.generateKeyPair(); // Encrypt data const ciphertext = await q0.encrypt(publicKey, plaintext); // Sign data const signature = await q0.sign(privateKey, message);

SECURITY PROTOCOLS

Q0 IMPLEMENTS SEVERAL SECURITY PROTOCOLS FOR SECURE COMMUNICATION AND DATA EXCHANGE. THE CORE PROTOCOL IS THE QUANTUM-RESISTANT TRANSPORT LAYER SECURITY (QR-TLS) PROTOCOL.

PERFORMANCE COMPARISON

THIS SECTION COMPARES THE PERFORMANCE OF QUANTUM-RESISTANT ALGORITHMS AGAINST CLASSICAL CRYPTOGRAPHY.

ALGORITHM KEY SIZE OPERATION SPEED QUANTUM RESISTANCE
RSA-2048 2048 bits 1.0x (baseline) VULNERABLE
ECC-P256 256 bits 10.5x faster VULNERABLE
KYBER-1024 12544 bits 0.8x slower RESISTANT
DILITHIUM-5 20736 bits 0.3x slower RESISTANT
AES-256 256 bits 1.0x (baseline) RESISTANT (128-bit quantum security)

ALTHOUGH POST-QUANTUM ALGORITHMS HAVE LARGER KEY SIZES AND SOMEWHAT SLOWER PERFORMANCE, THE SECURITY BENEFITS OUTWEIGH THESE DISADVANTAGES IN CONTEXTS WHERE LONG-TERM SECURITY IS CRITICAL.
