Cryptographic algorithms of reconfigurable implementation can improve the security, extensi bility and flexibility of the cryptographic communication, which have good potential to become a vital component in the future. However, at present most of the reconfigurable cipher chips have low coverage of algorithm.In this paper, on the basis of the analysis the structure of much cryptographic algorithm, summarizes the reconfigurable module set with high coverage of algorithm after a comprehensive comparison. Using the reconfigurable module set can reconfigure most generic cryptographic algorithms, such as DES, AES and SHA-1. Cipher algorithm based on the reconfigurable module set can solve the problem of low coverage well.
