1. method comprises:

  • Utilization is independent of other piece to a piece and carries out piece execution Advanced Encryption Standard (AES) computing of the operational pattern of computing to a plurality of fixed sizes, comprising;

    One group of k continuous blocks of the piece of the described a plurality of fixed sizes of storage in k register, k are more than or equal to the stand-by period (L) of AES samsara instruction, and described AES samsara instruction is used for the sequence of the AES samsara computing of AES samsara to described execution;

    AndBy the phase assigns an AES samsara instruction described that organized the sequence that k continuous blocks are carried out AES samsara computing concurrently weekly in the described k piece each.
