抄録

The RAM encryption encrypts the data on memory to prevent data leakage from an adversary to eavesdrop the memory space of the target program. In this paper, we discuss the feasibility of software based RAM encryption and clarify that it is possible to be secure against so-called semi-honest adversaries under some additional and reasonable constraints. In addition, we tentatively embed our RAM encryption mechanism to SHA-256 hash function. The performance evaluation results are also reported in this paper.------------------------------This is a preprint of an article intended for publication Journal ofInformation Processing(JIP). This preprint should not be cited. Thisarticle should be cited as: Journal of Information Processing Vol.28(2020) (online)DOI　http://dx.doi.org/10.2197/ipsjjip.28.473------------------------------
