时间分析攻击(Timing Attack):攻击者通过观察算法运行时间的微小差异,推测出加密过程中的关键数据。比如某个加密操作所需时间的长短可能与输入的密钥长度相关,攻击者就能根据这个差异猜出数据的类型或加密密钥,从而泄露密钥。 功耗分析攻击(Power Analysis Attack):攻击者通过测量设备在执行加密操作时的功耗变化,推测出加密...
旁道攻击Side-Channel Attacks
“That is why we created an ARC processor with SecureShield, which has some features added to prevent side-channel attacks,” adds Raucher. “The implementation of side-channel attack features can be turned on and off dynamically. You only use it when you are doing something sensitive. An op...
Side-channel attack A method of hacking a cryptographic algorithm based on the analysis of auxiliary systems involved in the encryption process. Unlike the classic decoding method, which focuses on mathematically modeling the key, aside-channel attackrelies on indirect data. ...

其实Side-channel attack 的原理并不复杂,就是通过对比某数据的访问延迟,从而推测出该数据是否被加载到 cache 中。 为了更形象地说明 Side-channel attack 的原理,我将讲述 Meltdown 论文中使用的,以 Flush-Reload 方式完成的攻击过程。 攻击的实现 为了简化项目难度,突出重点,我们假设要通过 Side-channel attack 手...
side-channel attack A side-channel attack is a security exploit that aims to gather information from or influence the program execution of a system by measuring or exploiting indirect effects of the system or its hardware -- rather than targeting the program or its code directly. Most commonly,...
