论文摘要
最近的幽灵攻击表明，现代的微体系式优化可能会使软件不安全。这些攻击使用管道，排序和猜测之类的功能，通过侧通道提取有关过程内存内容的信息。在本文中，我们证明了Cortex-A53受投机性泄漏的影响，即使微体系结构不支持排序的执行。我们命名了新的漏洞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.
