NVM-Shelf: Secure Hybrid Encryption with Less Flip for Non-Volatile Memory

Thomas Haywood Dadzie, Jiwon Lee, Jihye Kim, Hyunok Oh
2020 Electronics  
Since the CTR mode requires additional storage for the nonce, we classify write-intensive cache blocks and apply our CTR mode to the write-intensive blocks and apply the ECB mode for the rest of the blocks  ...  The Non-Volatile Memory (NVM), such as PRAM or STT-MRAM, is often adopted as the main memory in portable embedded systems.  ...  On the other hand, block access only supporting global memory limits SPM integration to the sequential architecture. These include NAND flash and some PRAM based memories.  ...
