Modern processor cores share the last-level cache and directory to improve resource utilization. Unfortunately, such sharing makes the cache vulnerable to cross-core cache side channel attacks. Recent studies show that information leakage through cross-core cache side channel attacks is a serious threat in different computing domains ranging from cloud servers and mobile phones to embedded devices. However, previous solutions have limitations of losing performance, lacking golden standards, requiring software support, or being easily bypassed.
