摘　　要：比较对称密码体制与非对称密码体制的特点,简述Triple DES算法与RSA算法的基本原理。在详细分析文件安全的相关问题和深入研究.NET Framework密码算法类的基础上,提出Triple DES算法与RSA算法结合运用的文件加密方案,设计系统的总体结构和基本流程,并以VB.NET实现了基于Triple DES与RSA的文件加密系统。实践表明,用本系统进行文件加密简单而方便。Comparing the characteristics of symmetric cryptography and asymmetric cryptography, this paper outlines the basic principles of the Triple DES algorithm and the RSA algorithm. On the basis of a detailed analysis of issues related to file security and in-depth study on . NET Framework encryption algorithm class, this paper proposes the file encryption scheme on the combi- nation of the Triple DES algorithm and the RSA algorithm, designs the system＇ s overall structure and the basic process, then the system is realized with VB. NET. After practice, the results show that the system is simple and convenient for file encryption.
