WebThe ARM940T has a 4KB DCache comprising 256 lines of 16 bytes (four words), arranged as four 64-way associative segments. The DCache uses the physical address generated by the processor core. It uses an allocate on read-miss policy, and is always reloaded a cache line (four words) at a time through the external interface. Webthey fail to systematically analyze all possible types of cache timing attacks in Arm processors, as does this work. 2.2 Three-Step Model for Cache Attacks Based on the observation that all existing cache timing-based side and covert channel attacks have three steps, a three-step model has been proposed previously by the authors [11].
