Central System: Embedded Core - Cortex-M4 / RISC-V

Cryptographic Nodes

  • In-Place NTT
  • Stack Squeeze
  • Flash DMA
  • True RNG
  • SecOC Node

Architectural Layers & Protocols

  • In-Place Polynomial Transform (NTT) (Optimized Cooley-Tukey & Gentleman-Sande Butterfly Networks): Performing fast modular polynomial multiplication within a single preallocated buffer
  • Flash-Resident Streaming Keccak (SHAKE-256) (Chunked State Absorbing and Squeezing): Streaming public matrix A generation directly into NTT computation without storing full matrices in RAM
  • Hardware Acceleration & Crypto Extensions (ARM Cortex-M55 / M85 Helium Vector Extensions & RISC-V Vector (RVV)): Accelerating vector operations while maintaining strict constant-time branchless execution
  • Automotive & Industrial Bus Layer (AUTOSAR SecOC & CAN FD Cryptographic Framing): Injecting truncated post-quantum MACs into 64-byte CAN FD frames without breaking bus latency

Key Metrics: <8 KB (Peak SRAM Stack Usage) | ARM M4/M33 (Target Architecture) | RISC-V Zk (Crypto Extension Support) | Zero-Leak (Side-Channel Timing Proof)

将后量子防护带入边缘芯片

Connected vehicles, smart meters, and industrial IoT sensors often operate with less than 64KB of RAM and cannot accommodate memory-heavy cryptographic implementations. EmbeddedPQC optimizes lattice mathematics for constrained microarchitectures.
