The Research Of Reconfigurable Processing Architecture For Fixed Multi-algorithms Block Cipher

The design of cipher processing system adopts reconfigurable technology, which can support many algorithms on the same hardware. Therefore, it can achieve processing with efficiency and flexibility,.and it will be widely used in military and commerce fields. This paper research the design of reconfigurable block cipher processing system.for many fixed algorithms combining AES,CRYPTON ,SERPENT.This paper has analysed the operation and processing structure characteristics of block cipher algorithms, and research fixed multi-algorithms cipher processing chip with Structure model,hardware composing,work flow,control module .This paper proposed resolve meas about fixed multi-algorithms cipher processing architectureThis paper researched design technology of fixed multi-algorithms reconfigurable cipher combining characteristics of AES,CRYPTON, SERPENT. This paper started with data processing flow of algorithms and designed.data processing route of algorithms,and started with data processing flow of key gengeration algorithms and designed data processing route of subke gengeration algorithms. This paper reconfigurable designed key module.For instance, shift operation unit, S-box substation unit and bit permutation unit.This paper has analysed the mapping of three block cipher algorithms on fixed multi-algorithms reconfigurable cipher processing architecture, evaluated clock cycle and throughput. The results prove that fixed multi-algorithms cipher processing architecture can guarantee high flexibility for algorithms application and can achieve relatively high performance.
