摘　　要：SMS4密码算法是我国自主研发的商用密码,使用软件对传输的信息进行加密,容易给攻击者采用分析程序、跟踪、反编译等手段进行攻击,而硬件加密算法比软件实现更快捷、更安全,本文提出了一种利用FPGA实现分组加密算法SMS4的硬件实现方法,通过ISE仿真验证了其正确性。SMS4 cipher algorithm is our self-developed commercial password. Using software to encrypt transmitted information,it is easy to apply analyzing procedures,tracking,decompiling and other attacking means by the attackers,but the hardware encryption algorithm is faster and safe than software. This paper presents a method of FPGA hardware to implement block cipher algorithm SMS4,by ISE simulator to verify its correctness.
