Abstract
1. Each of a plurality of data processing units independently performs an end-to-end encryption operation associated with AES on a data block. The number of data processing units is selected based at least in part on a desired processing throughput rate and power consumption, where the number of data processing units and the selected key length produce a total processing throughput rate that is a multiple of 1/10, 1/12 or 1/14 of a maximum throughput rate. A target data processing unit is selected, including by sequentially communicating with the data processing units in round-robin order to obtain an idle state information until an idle data processing unit is encountered. The target data processing unit generates a ciphertext data block corresponding to the target data block, including by performing all SubByte, ShiftRow, MixColumn, and AddRoundKey transformations.
