(MyBroadband) MIT researchers have developed a novel cryptography circuit that can be used to protect low-power “internet of things” (IoT) devices in the coming age of quantum computing.
Today’s most quantum-resistant encryption scheme is called “lattice-based cryptography”. But these schemes are way too computationally intense for IoT devices, which can only spare enough energy for simple data processing.
MIT researchers recently described a novel circuit architecture and statistical optimization tricks that can be used to efficiently compute lattice-based cryptography. The 2-millimeter-squared chips the team developed are efficient enough for integration into any current IoT device.
