摘　　要：通过将AES算法模块化、运算一般化,给出了类AES算法的统一框架。在此框架下不仅可以同时实现AES的加密、解密,而且可以通过外部参数动态设定分组算法,使得密码算法的使用更加灵活、安全。给出了算法的FPGA实现。结果表明设计方案可行,速度较高。AES algorithm was modularized and the operation of it was generalized. A unified framework was proposed for block cipher resembling AES algorithm. In this framework, not only AES encryption or decryption can be realized, but also the specific block cipher algorithm can be set through external parameters. The use of eryptographic algorithms is more flexible and security. FPGA realization for the unified framework was also given. The testing results show the scheme is feasible and has a higher speed.
