摘要:In November 2001 NIST published Rijndael as the proposed algorithm for AES(AdvancedEncryption Standard). The result of new attack methods shows that there may be some missing part inthe design of S-box and key schedule with AES algorithm. The problem is the weakness of linearityexisting in the S-box and key schedule. In order to keep away from the new attacks and implement theAES in software and hardware provides higher level of security and faster encryption speed; we analyzein detail the AES algorithm and propose a new implementation scheme for increasing complexity ofnonlinear transformation in design of S-box. Implementation scheme with Java and the use ofreconfigurable coprocessor as a cryptography hardware is proposed
