Abstract:

Spectre can be fixed in hardware by treating speculative microarchitectural state in the same way as speculative architectural state: On mis-speculation throw away all the speculatively-performed changes. The resource-contention side channel needs to be closed, too. This position paper also explains how Spectre works, why software mitigations are not sufficient.
