It monitors the physical information leaked by Cache during program execution, then combines some statistical methods to analyze the information, and finally achieves the theft of private information. The typical scenario of attack is shown in Fig. 2.
WebbThis invention proposes a novel random fill cache architecture that mitigates reuse-based attacks, and does not degrade performance. It can also be used to reduce cache miss rate and improve performance for the existing processor caches for some special applications.
