Abstract The imperative for a structured transition to post-quantum cryptography (PQC) stems from the prospective capability of fault-tolerant quantum computers to execute Shor’s algorithm, thereby compromising RSA and ECC public-key systems through efficient factorization and discrete logarithm computation, alongside Grover’s algorithm yielding quadratic speedup against symmetric encryption, effectively reducing AES-256 security to approximately AES-128 levels. … Leggi tutto Post-Quantum Cryptography Transition: Bletchley-Inspired Domestic Execution and Allied Certification in 2025
