Core engineering and protocols for Energy-Harvesting IoT Security.
Trillions of future IoT sensors (in agriculture, smart cities, and industrial structural health monitoring) will operate without chemical batteries, powered entirely by ambient solar cells, thermal gradients, or ambient RF energy harvesting. These devices experience frequent power interruptions whenever ambient energy drops.
PQCEmbedded incorporates non-volatile ferroelectric RAM (FRAM) state checkpointing: the cryptographic pipeline stores intermediate polynomial vector states in non-volatile registers after every NTT stage. If power fails mid-handshake, the device resumes computation immediately upon power restoration without restarting the cryptographic operation from scratch.
