AH-KEM: Adaptive Hybrid Key Encapsulation Mechanism for Post-Quantum Secure Cloud Communication
Classical public-key cryptography (RSA-2048, ECDH) is vulnerable to Shor's algorithm on quantum computers, with harvest-now-decrypt-later threats already targeting archived cloud traffic for future decryption. While NIST's 2024 ML-KEM (FIPS 203) and ML-DSA (FIPS 204) standards provide quantumresistant primitives, unifo...
