EmbeddedShield: Treillis de Silicium Actifs, Détection de Glitches et Microcontrôleurs Sécurisés

EmbeddedShield fournit des cœurs IP RTL, des architectures de masquage arithmétique d'ordre supérieur et des circuits de détection de fautes pour immuniser les ASIC et microcontrôleurs FIPS 203/204 contre les attaques DPA et les injections de fautes de tension ou d'horloge.

EmbeddedShield Silicon Architecture & Side-Channel Masking Topology

Higher-order polynomial masking engine, dual-rail pre-charge logic, and optical fault sensor

Central System: Shielded Crypto Engine - Masked Lattice ALU

Cryptographic Nodes

  • Random Mask Generator
  • Masked NTT Multiplier
  • Dual-Rail Asynchronous ALU
  • Photodiode Glitch Sensor
  • Clock Jitter Generator

Architectural Layers & Protocols

  • Differential Logic Plane (Sense-Amplifier-Based Logic (SABL) / Dual-Rail): Ensuring identical power consumption for logic 0 and logic 1 transitions across all clock cycles.
  • Algorithmic Polynomial Masking (First-Order and Second-Order Arithmetic Masking): Splitting lattice coefficients into random shares (x = x_A + x_B mod q) throughout NTT pipelines.
  • Active Physical Fault Sensors (Substrate Light Diodes & Voltage Spike Detectors): Detecting laser fault injection (LFI) and power supply glitching during cryptographic execution.
  • Execution Time Randomization (Randomized Shuffling & Dummy Instruction Insertion): Decorrelating electromagnetic radiation traces from algorithmic execution order.

Key Metrics: Order-2 (Higher-Order Masking Target) | > 5M Traces (DPA Resistance Threshold) | < 1.5 ns (Glitch Detection Latency) | Zero Branch (Fault-Resilient State Machine)
