摘　　要：由于电子商务拥有了更加丰富的信息、更加简单方便的交易和更加低廉的成本,受到了广大用户的欢迎。然而,现今阻碍电子商务快速发展的最大问题则是安全问题,数据加密技术是保证电子商务安全的核心技术,是电子商务安全技术的重要组成部分。目前使用的数据加密技术主要分成两种:对称加密技术和非对称加密技术。文章通过剖析数据加密技术中的RSA和DES算法的特点和缺点,提出一种混合加密算法用以规避两者的缺陷。The reasons why E-commerce is popular among the huge number of the users are that it provides them for more information, the simple transaction and the cheaper cost. However, in present time security is the important barrier to the development of E-commerce.Also, data encryption is the core technology to ensure the E-commerce security, and it is an essential part of its safety technics. Nowadays there are two kinds of encryption techniques,and they are symmetric and asymmetric encryption techniques. This paper analyzed the advantages and disadvantages of RSA and DES algorithm which is used for data encryption,then proposed a hybrid encryption algorithm to avoid the deficiency between both of them.
