A Security RISC? The State of Microarchitectural Attacks on RISC-V

Microarchitectural attacks threaten the security of computer systems even in the absence of software vulnerabilities. While x86 and ARM CPUs have been extensively studied, the rising popularity of RISC-V CPUs demands a thorough examination of their microarchitectural attack surface. With the standardization of the RISC-V instruction set architecture and the announcement of support for the architecture by major processor vendors, RISC-V CPUs are on the verge of becoming ubiquitous. In this talk, we will show a systematic investigation of the …
