摘　　要：分组密码算法是信息加密处理的重要算法。分组密码平台是一种实现密码算法的处理器。分组密码在设计上可采用存储逻辑或布线逻辑,二者在实现上分别依赖微处理器和数字逻辑电路。通过分析分组密码算法的特点和分组密码的设计准则、安全性准则,针对基于存储逻辑的算法和基于布线逻辑的算法特点,提出设置特殊函数运算指令,将多种不同逻辑类型的密码运算因子以单一的指令形式实现,在处理器上以指令形式在一个平台上实现,解决了不同算子在同一平台上高效计算问题。The block cipher algorithm is an important algorithm for the processing of information encryption. The block cipher platform is a processing device for implementing the encryption algorithm. The block cipher can be designed by using storage logic or wired logic,which are implemented based on microprocessors and digital logic circuits respectively. By analyzing the characteristics of block ciphers and its design criteria, this paper proposes an implement method that sets the special functions operation instruction to implement many different types of cryptographic operations factor in a single instruction. This method can realize the efficient computa- tion of different operators on the same platform.
