A type of side-channel attack to processors that uses side-effects of transient instructions. Transient instructions are executed speculatively but are later discarded (they not part of the program execution at the ISA abstraction level).
Security used to be about systems and software. As threats evolve, hardware engineers also have to familiarize themselves with trust and security terms and acronyms. If you are a hardware engineer interested in hardware trust and security, be sure to bookmark this page. If you spot a mistake or have ideas for enhancements, please get in touch.
