| # | Contribution | |---|--------------| | 1 | Definition of an tailored to the MPO1‑MP5’s hardware constraints (256 KB dual‑bank flash, 2 MHz SPI). | | 2 | Implementation of a lightweight post‑quantum key exchange (FrodoKEM‑640) and AEAD (AES‑GCM‑SIV) that fits within the 32 KB RAM budget. | | 3 | Design of a dual‑bank flash management scheme guaranteeing atomic switch‑over without reboot cycles. | | 4 | Comprehensive security analysis (formal verification of state machine, resistance to replay and downgrade attacks). | | 5 | Empirical evaluation of performance , reliability , and energy consumption under extreme temperature and RF‑interference conditions. |
Significant reduction in call echo and improved mic clarity. Stability:
