Abstract: A system and method for defense against cache timing channel attacks using cache management hardware is provided. Sensitive information leakage is a growing security concern exacerbated by shared hardware structures in computer processors. Recent studies have shown how adversaries can exploit cache timing channel attacks to exfiltrate secret information. To effectively guard computing systems against such attacks, embodiments disclosed herein provide practical defense techniques that are readily deployable and introduce only minimal performance overhead. In this regard, a new protection framework against cache timing channel attacks is provided herein by leveraging commercial off-the-shelf (COTS) hardware support in processor caches, including last level caches (LLC), for cache monitoring and partitioning. This framework applies signal processing techniques on per-domain cache occupancy data to identify suspicious application contexts.

The periods of the input clocks are all a first period, and the periods of the output clocks are all a second period. The first period is smaller than the second period. The frequency dividing circuit and the retiming circuit operate according to a mode control signal which determines a ratio of the first period to the second period.
