    • A block cipher algorithm based encryption processing method comprises the following steps: external key registration, external data registration, key expansion, data encryption conversion, internal data registration, and data iteration processing, which solves the problems of the prior ciphering method based on block cipher algorithm, such as low ciphering efficiency and high implementation cost, and efficiently reduces the resource consumption under the premise of keeping the high efficiency of the prior art, thereby reducing the implementation cost of the device. When the number of the conversion component is 1, the resource consumption is only about 60 percent of the prior art; and when the number of the conversion component is 2, the resource consumption is only about 70 percent of the prior art. The present invention increases a sub-key registration unit, which can reduce the critical paths and increase the clock dominant frequency of the ciphering equipment during the implementation of integrated circuits, thereby improving the ciphering capacity of the inventive method.
