高速缓存侧信道攻击对计算机系统安全构成了现实威胁。之前的工作称为Cloak,利用商品硬件事务性内存(HTM)来保护敏感数据和代码免受缓存侧信道攻击。然而,Cloak需要程序员对易受攻击的软件进行繁琐且容易出错的手工修改。本文介绍了scape,一个编译器分析和转换,它可以利用Cloak的防御功能,自动地保护程序免受缓存侧信道攻击。一项评估表明,斗篷提供了与斗篷一样强大的保护,同时与斗篷竞争。
Cache side-channel attacks pose real threats to computer system security. Prior work called Cloak leverages commodity hardware transactional memory (HTM) to protect sensitive data and code from cache side-channel attacks. However, Cloak requires tedious and error-prone manual modifications to vulnerable software by programmers. This paper presentsCape, a compiler analysis and transformation that soundly and automatically protects programs from cache side-channel attacks using Cloak’s defense. An evaluation shows that Cape provides protection that is as strong as Cloak’s, while performing competitively with Cloak.
