MIT researchers have developed a tiny, ultra-efficient ASIC microchip that brings post-quantum cryptography (PQC) to power-constrained wireless biomedical devices such as pacemakers and insulin pumps. The chip implements two PQC schemes simultaneously for redundancy, includes an on-chip true random number generator, adds countermeasures against power side-channel attacks on the most vulnerable operations, and incorporates early fault detection for voltage glitches. The result is 20–60x better energy efficiency compared to prior PQC implementations, with a compact footprint suitable for edge devices beyond biomedical applications.
