Speculative Taint Tracking (STT): A Comprehensive Protection for Speculatively Accessed Data

Recent security vulnerabilities that target speculative execution (e.g., Spectre) present a significant challenge for processor design. These highly publicized vulnerabilities use speculative execution to learn victim secrets by changing the cache ...

Speculative execution attacks are an enormous security threat. In these attacks, malicious speculative execution reads and exfiltrates potentially arbitrary program data through microarchitectural covert channels. Correspondingly, prior work has shown ...

Speculative execution attacks present an enormous security threat, capable of reading arbitrary program data under malicious speculation, and later exfiltrating that data over microarchitectural covert channels. This paper proposes speculative taint ...
