Overview

Randomized trial shows faster post-quantum encryption in embedded systems, indicating viable future applications.

Key Points

  • This research aims to improve entropy distribution in embedded systems using quantum-derived sources.
  • Developed a Quantum Entropy as a Service (QEaaS) system for ESP32-class clients.
  • Integrated quantum random number generation (QRNG) and post-quantum secured communication using DTLS 1.3.
  • Benchmark tests performed on ESP32 hardware targeting multiple configurations.
  • ML-KEM-512 achieves an average DTLS handshake time of 313 ms without certificate verification, 35% faster than ECDHE P-256.
  • Pairing ML-KEM-512 with ML-DSA-44 reduces handshake time to 225 ms.
  • The fully post-quantum configuration is 63% faster than the classical ECDHE P-256 with ECDSA, even with full verification.
