Dual Composite Field Advanced Encryption Standard Memory Encryption Engine

摘要

A different set of polynomials may be selected for encryption and decryption accelerators. That is, different sets of polynomials are used for encryption and decryption, each set being chosen to use less area and deliver more power for a memory encryption engine. This is advantageous in some embodiments since memory read operations are typically more critical and latency sensitive than memory writes.
