ISSCC 2018: MIT’s low-power hardware crypto RISC-V IoT processor

March 17, 2018May 25, 2021 David Schor 65nm, crypto engine, DTLS, edge computing, IoT, ISSCC, ISSCC 2018, MIT, RISC-V

In recent years, IoT devices have been plagued with security issues. Memory and energy constraints of those low-power devices mean there is very little headroom for complex security implementations. At ISSCC 2018, a team of MIT researchers has attempted to address this problem with their low-power fully in-hardware crypto engine IoT RISC-V processor.
