Memory encryption is used in many devices to protect memory content from attackers with physical access to a device. However, many current memory encryption schemes can be broken using differential power analysis (DPA). In this work, we present Meas-the first Memory Encryption and Authentication Scheme providing security against DPA attacks. The scheme combines ideas from fresh re-keying and authentication trees by storing encryption keys in a tree structure to thwart first-order DPA withoutdoi:10.1007/s13389-018-0180-2 pmid:31231603 pmcid:PMC6555441 fatcat:5kuetrwwwnf7rkdhctgkpj46wa
