MLKEMSec Microarchitectural Defense & Cache-Invariance Pipeline

Constant-time memory scheduling, speculative execution barriers, and cache flush engines

Central System: Cache Defense Unit - Microarchitectural Guard

Cryptographic Nodes

  • Twiddle Factor Prefetcher
  • Speculative Execution Barrier
  • Vectorized Montgomery ALU
  • Cache Flush Controller
  • Transient Fault Monitor

Architectural Layers & Protocols

  • Cache Architecture Invariance (Cache-Line Locking & Linear Memory Scans): Eliminating cache hit/miss timing differences during polynomial table lookups.
  • Transient Execution Hardening (Speculative Load Hardening & Serialization Barriers): Preventing Spectre-V1/V2 and Meltdown transient data leakage during decapsulation.
  • Constant-Time Assembly Pipeline (Hand-Written Assembly with Zero Branching): Ensuring every instruction executes in fixed cycle counts regardless of secret values.
  • Multi-Tenant Cloud Isolation (Core Pinning & Cache Allocation Technology (CAT)): Shielding post-quantum cryptographic containers from cross-core noisy neighbor attacks.

Key Metrics: 0 Cycle (Timing Variance Across Inputs) | Spectre-Proof (Speculative Execution Immunity) | L1 Locked (Twiddle Factor Memory Security) | 100% (Constant-Time Assembly Coverage)
