An efficient stream cipher for resistive RAM

Abstract

Resistive Random Access Memory (RRAM) is considered as one of the most competitive candidate for next-generation embedded system memories but data security for it has not yet been studied in detail. Since data security of embedded system is becoming more and more important nowadays, we think that it is necessary to study about data encryption for RRAM. In this paper, we studied data encryption candidates for RRAM and conducted several stream ciphers performance experiments for RRAM. As a consequence, we showed that Trivium is the most suitable stream cipher algorithm for RRAM. Also, we analyzed the experimental results.
