"Intel Proposes New SAPM Memory Type to Protect Against Spectre-Like Attacks"

Intel recently published a paper in which details about a new type of computer memory were shared. The new type of CPU memory, called Speculative-Access Protected Memory (SAPM), was designed to protect against Spectre, Meltdown, Zombieload, and other speculative execution side-channel attacks. Speculative execution side-channel attacks refer to vulnerabilities deriving from the prediction of future instructions by high-performance microprocessors. Misspeculations leave traces of information behind that could be exploited via side-channels by hackers to gain access to sensitive data stored in memory. A team of researchers at Intel STORM (Strategic Offensive Research and Mitigation) have proposed the replacement of the current CPU memory system with SAPM. SAPM will work as an alternative to existing hardware and software-level mitigations. This article continues to discuss speculative side-channel attacks as well as the new SAPM memory type proposed by Intel to protect against such attacks.
