Abstract
A scheduler is used to control a target data processing unit among a plurality of data processing units in order to receive a target data block that is to be encrypted. Each of the plurality of data processing units is able to independently complete an encryption operation associated with Advanced Encryption Standard (AES) for a data block. A ciphertext data block corresponding to the target data block is generated, including by performing the encryption operation associated with AES on the target data block using the target data processing unit.
Claims12
A system, comprising:
- a memory;
- and
- a processor coupled to the memory, wherein:
- there is a plurality of data processing units where each of the plurality of data processing units independently performs an end-to-end encryption operation associated with Advanced Encryption Standard (AES) on a data block;
- the processor selects a selected key length, from a plurality of supported key lengths associated with the AES;
- the processor selects a number of data processing units to have in the plurality of data processing units based at least in part on a desired processing throughput rate and power consumption, wherein the number of data processing units and the selected key length produce a total processing throughput rate, collectively for the plurality of data processing units, that is a multiple of one or more of the following:
- 1/10, 1/12 or 1/14 of a maximum throughput rate;
- and
- the processor selects a target data processing unit, from the plurality of data processing units, to:
- receive a target data block that is to be encrypted, including by:
- sequentially communicating with the plurality of data processing units in a round-robin order to obtain an idle state information until an idle data processing unit in the plurality of data processing units is encountered;
- and
- selecting the idle data processing unit to be the target data processing unit;
- and
- generate a ciphertext data block corresponding to the target data block, including by performing the end-to-end encryption operation associated with AES, including all SubByte transformations, all ShiftRow transformations, all MixColumn transformations, and all AddRoundKey transformations on the target data block.
