摘　　要：将可重构的概念引入密码算法设计中,创造性地提出密码算法簇的概念,通过密钥控制密码算法结构变化,不但提高了密码算法的灵活性,同时也适应了多层次不同用户的安全需求。分析了密码算法簇的安全性和实现效率,并结合AES算法给出了一个密码算法簇的例子。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.
