最近的Spectre攻击表明，现代微架构优化可能会使软件不安全。这些攻击使用流水线、乱序和推测等特征，通过边通道提取有关进程内存内容的信息。在本文中，我们证明了Cortex-A53受到投机性泄漏的影响，即使微架构不支持乱序执行。我们将这类新的漏洞命名为SiSCloak。
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.
