Abstract: The reconfiguration idea was introduced into the design of cryptography algorithms, and the concept of cipher cluster was creatively proposed. Variation of cipher architecture was controlled by keys, which could not only enhance flexibility of algorithms but also suite to security needs of different users at variety levels. Security and performance of cipher cluster were analyzed, and a paradigm was given using AES cipher.

Key words: Cipher cluster, Reconfigurable, One-time-pad
