To Prevent Information Leakage from Cache Attacks
TOKYO–(BUSINESS WIRE)–#TechforGood—NTT Corporation (NTT) in collaboration with the Research Institute of Electrical Communication, Tohoku University and CASA (Cyber Security in the Age of Large-Scale Adversaries) at Ruhr University Bochum has developed a dedicated cache random function to eliminate the vulnerability caused by delay differences with the cache which is generated in the event of acquiring and updating data between CPU memories. This research contributes to the realization of a highly secure CPU that prevents information leakage due to cache attacks.
NTT designed and proposed a Secure Cache Randomization Function (SCARF) for randomization of cache index and formulated what type of function is suitable for randomizing of cache index[1] by providing design guidelines for randomization of cache function which formulated appropriate random function. This paper will be accepted and presented at USENIX Security ’23※
