Architectural Layers & Protocols

  • Parallel NTT Hardware Pipeline (Dedicated Dual-Radix Butterfly Execution Units): Performing polynomial modular reduction and butterfly calculations in single clock cycles
  • True Random Number Generator (TRNG) & Entropy Pool (Ring-Oscillator Jitter Entropy with NIST SP 800-90B Validation): Generating high-entropy seeds for centered binomial distributions and polynomial noise vectors
  • Physical Countermeasures & Tamper Sensors (Active Metal Shields, Voltage Glitch Detectors & Optical Sensors): Triggering instant key zeroization when laser fault injection or clock glitching is detected
  • System-on-Chip (SoC) Bus Interconnect (AXI4-Lite & APB Secure Peripheral Interface): Integrating directly with ARM TrustZone, RISC-V PMP, and confidential computing domains

Key Metrics: <12 µs (ASIC Decapsulation Latency) | 25k Gates (Silicon Area Footprint) | Order-2 (Side-Channel Masking Order) | 100% (Glitch & Laser Tamper Defense)

なぜソフトウェアのみのポスト量子暗号では不十分なのか

General-purpose CPUs executing lattice arithmetic suffer from microarchitectural timing variations, cache contention, and power leakage. Dedicated silicon hardware cores isolate private keys within physical boundaries and guarantee constant-time operation.
