Reducing the overhead of authenticated memory encryption using delta encoding and ECC memory
Salessawi Ferede Yitbarek, Todd M. Austin · 2018
Data stored in an off-chip memory, such as DRAM or non-volatile main memory, can potentially be extracted or tampered by an attacker with physical access to a device. Protecting such attacks requires storing message authentication codes and counters - which incur a 22% storage overhead. In this work, we propose techniques for reducing these overheads.
