First, it analyses the domestic and international research status briefly, and surveys the automobile sales company, in order to establish the development needs of this website. Second, based on demand analysis, this paper selected the Microsoft Visual Studio2005as the development tools, the Microsoft. NET Framework SDK3.0as the development environment, SQL Server as the back-end database, used the C#language, and described key technologies like B/S system architecture, ASP.NET and back-end database in detail, etc. Again, various modules of the website and data tables in the database is designed and implemented in the paper. Finally, for the current e-commerce website password crack, SQL injection attacks and other security issues, this paper uses the following three Strategies:the improvement on the basis of MD5encryption technology to encrypt the password of the user input to prevent the dictionary attacks; using parameterized queries to prevent SQL injection attacks; designing the three protection model in the B/S system, and formatting three-detection measure, to defense against unlawful attacks comprehensively.
