Design and Implementation of a Secure RISC-V Microprocessor. (arXiv:2205.05095v1 [cs.CR])

Secret keys can be extracted from the power consumption or electromagnetic
emanations of unprotected devices. Traditional counter-measures have limited
scope of protection, and impose several restrictions on how sensitive data must
be manipulated. We demonstrate a bit-serial RISC-V microprocessor
implementation with no plain-text data. All values are protected using Boolean
masking. Software can run with little to no counter-measures, reducing code
size and performance overheads. Unlike previous literature, our methodology is
fully automated and can be applied to designs of …
