Countermeasures against a side-channel attack in a kernel memory

Na-Young Ahn and Dong Hoon Lee

Abstract: We proposed a zero-contention in cache lines a cache policy between REE and TEE to prevent from TruSpy attacks in a kernel memory of an embedded system. We suggested that delay time of data path of REE is equal or similar to that of data path of TEE to prevent timing side-channel attacks.
