Abstract

See full text

Systems and methods related to flush plus reload cache side-channel attack mitigation are described. An example method for mitigating a side-channel timing attack in a system including a processor having at least one cache is described. The method includes receiving a first instruction, where the first instruction, when executed by the processor, is configured to flush at least one cache line from the at least one cache associated with the processor. The method further includes, prior to execution of the first instruction by the processor, automatically mapping the first instruction to a second instruction such that the at least one cache line is not flushed from the at least one cache even in response to receiving the first instruction.
