| Abstract: | 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. |
