摘要 探讨了长度大于256比特明文和密钥的Rijndael密码扩展算法,分析了扩展Rijndael算法的输入明文和密钥的排列规则和随后轮处理中各个步骤采用的处理方法,提出了一种通过Ri-jndael算法自身加密密钥来增强扩展密钥安全性的方法,介绍了Rijndael算法的JAVA软件实现和其核心模块的JAVA编程。 A expansive Rijndael algorithm that plain text and key are longer than 256 bits is discussed in this paper. The regulating arrangement of input plain text and key in expansive Rijndael algorithm and the dealing with the steps of round are analyzed. A method is proposed to increase the security of expansive key through encrypting the key by Rijndael algorithm itself. Then the program of algorithm based on JAVA and the kernel model of programs are introduced.
