Abstract: ABSTRACT POST-QUANTUM CRYPTOGRAPHY ENABLED BLOCKCHAIN-BASED DIGITAL IDENTITY SYSTEM A computer-implemented system (200) for digital identity management using NIST-standardized post-quantum cryptographic algorithms and blockchain distributed ledger technology is disclosed. The system comprises a processor (220), a memory (210), and modules including a post-quantum key generation module with ML-KEM-768 (100) and ML-DSA-65 (110) components providing 192-bit quantum security, an identity registration module (230) for collecting and encrypting identity attributes, a blockchain transaction module (120) interfacing with blockchain network (260), a hybrid storage module (130) and IPFS storage module (140) implementing three-tier architecture with on-chain verification, off-chain IPFS encrypted storage on network (270), and local key storage, an identity verification module (240) completing verification in 2-3 seconds, a selective disclosure module (150) generating 200-byte zero-knowledge proofs, a side-channel protection module (160) implementing constant-time operations verified over one million traces, and a compliance verification module (170) achieving simultaneous RBI KYC, GDPR, and NIST FIPS 203/204 compliance. The system provides quantum-resistant digital identity management with 20+ year security and cost-efficient operations. [
