Memory Encryption for General-Purpose Processors
IEEE Security and Privacy, 2016 Intel's Software Guard Extensions allows general-purpose computing platforms to run software in a trustworthy manner and securely handle encrypted data. To satisfy the technology's security goals, the external system memory must be cryptographically protected. A new hardware unit added to the processor's memory controller--the Memory Encryption Engine (
