Speculative Leakage in ARM Cortex-A53

Year: 2020

Type: preprint

Abstract: The recent Spectre attacks have demonstrated that modern microarchitectural optimizations can make software insecure. These attacks use features like pipelining, out-of-order and speculation to extract information about the memory contents of a process via side-channels. In this paper we demonstrate that Cortex-A53 is affected by speculative leakage even if the microarchitecture does not support out-of-order execution. We named this new class of vulnerabilities SiSCloak.
