摘要:
A processing apparatus comprises logic to, according to a selected secure hash algorithm (SHA) algorithm, generate hash values by preparing message schedules for a plurality of message blocks in parallel using single instruction multiple date (SIMD) instructions and performing compression in serial, and logic to generate a message digest conforming to the secure hash algorithm (SHA) algorithm.
