摘要
Apparatus and methods are disclosed for mitigating speculation-based attacks on processors. In one example of the disclosed technology, an apparatus includes a processor having memory situated to store profiler data for measuring at least one performance criteria for an instruction stream executed by the processor and control logic configured to, based on the measure performance criteria, select one of the plurality mitigation schemes to mitigate expectation-based attack on the apparatus. The apparatus can include a remediation unit that can prevent speculative side effects by implementing a delay scheme, a redo scheme, or an undo scheme which prevents side effect data generated by mis-speculated instructions from becoming visible to an attacker.
