动态口令认证的网上选课系统的设计与实现 摘 要 将计算机引入教学信息管理已经成为高校教学管理工作的重要内容之一，比如实行网上选课。与传统的选课方式相比，网上选课提高了学生选课效率，增加了学生选课自主权，使教学更加透明，同时大大提高了教务管理工作的效率。 本文设计实现的网上选课系统基于ASP.NET平台进行开发，后台由SQL Server 2000数据库支持，通过使用C#语言实现动态网页的效果，达到对数据库的操作以完成使用者的要求。本系统主要由以下几个模块组成：身份验证模块；选课模块；信息管理模块等。用户只需要通过浏览器访问就可以实现选课操作，操作简单灵活。并且本系统登录时使用动态口令进行身份认证，解决了静态口令所遇到的很多攻击性问题，如：网络数据流窃听、字典攻击、穷举攻击等，增加了系统安全性。 关键词：网上选课系统； 动态口令；C#；ASP.NET Design and Implementation of Web-basedCourse Selecting System with Dynamic Password Authentication Abstract Applying computer to manage the teaching informationis one of the important parts of the university management, such as courseselecting on internet. Comparing to the traditional course selecting method, courseselecting on internet saves more resources, at the same time, it enhances thestudents’ independence when choosing courses, which makes the teaching moretransparent, also greatly increases the efficiency of teaching management. This paper designs a Web-based Elective System, whichbases on the platform of ASP.NET; the database is SQL Server 2000. We use C#language to achieve the front page movement effect. This system mainly iscomposed of following several modules: ID authenticating module; courseselecting module; information management module. The user just through IEexplore to realize the course selecting operation, the operation is simple andflexible. This system adopts Dynamic Password to authenticate ID when login in,it prevents many problems of the static password, for example Sniffer,Dictionary attack, Brute Force and so on. The Dynamic Password improves thesafety of the system. Key words: Online Course Selecting System; DynamicPassword; C#; ASP.NET
