摘　　要：随着计算机技术的飞速发展,传统的数据加密标准DES算法渐被新的高级加密标准AES--Rijndael算法所替代。根据Rijndael算法中大量矩阵运算的特点,对加密和解密的轮变换进行了研究,给出了其优化实现,提高了AES算法的加解密速度;实践证明,该应用方法是有效的。With the rapid development of computer technology, the data encryption standard DES was replaced by the AES-Rijndael algorithm of the advanced encryption standard,This Paper studies its round transformation equation ,and gives a better implementation of AES based on table- looking-up method ,proposes its optimized algorithm,which can greatly increase the enerypting/decrypting speed. And practical application proves that this method is effective.

关 键 词：密钥 RIJNDAEL 轮变换
