<p>The RAM encryption encrypts the data on memory to prevent data leakage from an adversary to eavesdrop the memory space of the target program. The well-known implementation is Intel SGX, whose RAM encryption mechanism is definitely hardware dependent. In contrast, Watanabe et al. proposed a fully software-based RAM encryption scheme (SBRES). In this paper, we developed the tools for embedding the SBRES in C source codes for its practical application. We applied the tools to the source codes of some cryptographic implementations in Mbed TLS and confirmed that the tools successfully embedded the SBRES functionality in the cryptographic implementations.</p>

Language：English Publishing type：Research paper (scientific journal) Publisher：一般社団法人 情報処理学会 Joint Work
<p>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.</p>
