TECHNOLOGIES FOR MEMORY CONFIDENTIALITY, INTEGRITY, AND REPLAY PROTECTION

摘要

Technologies for memory encryption include a computing device to generate a keyed hash of a data line based on a statistical counter value and a memory address to which to write the data line and to store the keyed hash to a cache line. The statistical counter value has a reference probability of incrementing at each write operation. The cache line includes a plurality of keyed hashes and each of the keyed hashes corresponds with a different data line. The computing device further encrypts the data line based on the keyed hash, the memory address, and the statistical counter value.
