Central System: ML-KEM Core Engine - FIPS 203 Ring Arithmetic

Cryptographic Nodes

  • Ring R_q (q=3329)
  • NTT Transform
  • M-LWE Matrix
  • FO Transform
  • SHAKE-256 PRF

Architectural Layers & Protocols

  • Polynomial Ring Arithmetic (R_q = Z_3329[X]/(X^256 + 1)): Fast polynomial multiplication using the Number Theoretic Transform (NTT)
  • Module Learning With Errors (M-LWE) (Matrix A in R_q^(k x k) with Noise Vectors e, s): Injecting cryptographic noise to prevent lattice reduction algorithms (BKZ)
  • Fujisaki-Okamoto Chosen-Ciphertext Transform (Deterministic Re-Encryption Verification): Converting IND-CPA public-key encryption into IND-CCA2 key encapsulation
  • Constant-Time Implementation & Microarchitecture (AVX2 / AVX-512 / ARM Neon Vectorized Kernels): Zero branch dependencies on secret data to eliminate cache and timing leaks

Key Metrics: q = 3329 (Prime Modulus) | n = 256 (Ring Degree) | k = 3 (ML-KEM-768 Dimension) | Constant-Time (Timing Attack Resistance)

El Cimiento Global para el Intercambio de Claves Poscuánticas

Derived from the CRYSTALS-Kyber submission, ML-KEM standardizes key encapsulation over polynomial rings R_q = Z_q[X]/(X^256 + 1) with q = 3329. Its mathematical hardness stems from the hardness of the Module Learning With Errors (M-LWE) problem.
