SoK: Hardware Defenses Against Speculative Execution Attacks. (arXiv:2301.03724v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Speculative execution attacks leverage the speculative and out-of-order
execution features in modern computer processors to access secret data or
execute code that should not be executed. Secret information can then be leaked
through a covert channel. While software patches can be installed for
mitigation on existing hardware, these solutions can incur big performance
overhead. Hardware mitigation is being studied extensively by the computer
architecture community. It has the benefit of preserving software compatibility
and the potential for much smaller performance …
