摘　　要：针对密码处理领域广泛应用的分组密码算法和单向散列算法研究支持多种算法的密码处理结构.在对多种密码算法的结构和操作特点进行详细分析的基础上提出并实现了能够对多种密码算法提供加速支持的对称密码处理结构(CryptoPro).评估了分组密码算法和单向散列算法在CryptoPro上运行的性能,并与国外类似的密码处理结构进行了比较.评估结果说明CryptoPro既能保证各类密码算法应用的灵活性又能达到较高的性能.A general purpose cipher processing architecture dedicated to major block ciphers and one-way hash algorithms which are widely used in many fields was proposed. Base on the extracted characteristics of the cryptographic algorithms a symmetric cipher processing architecture （CryptoPro） which can improve the performance of many block ciphers and one-way hash algorithms was implemented. The algorithmst performance on CryptoPro was evaluated and the result was compared with the similar architecture abroad. These results proved that CryptoPro can achieve relatively high performance for many cryptographic algorithms with high flexibility.
