摘  要
随着网络技术的迅速发展，传统的投票方式已经不能满足人们的需要。而网上投票系统除了能够完成传统的功能之外，更具有时效高和范围广的优点，更符合现代社会的需要。
具有动态口令认证机制的网上投票系统的设计是采用ASP和SQL Server2000技术开发的简易投票系统，并在用户登陆过程中设置动态验证码，提高系统的安全性。它实现了以下功能:投票、结果查看、增加、删除及搜索投票等。本论文首先介绍了网上投票系统的概念及和适用范围。在系统开发环境中主要对ASP、SQL和动态口令认证机制的基本概念作了详尽的介绍。接着通过E-R图说明数据库的搭建和数据库的设计。然后介绍了本系统的总体设计，包括：系统结构和总体功能设计。论文以功能模块图的形式说明了功能的设计并给出了部分核心代码及主要功能界面图。

The design of the on-line vote system with the dynamic password authentication scheme
Abstract
With the rapid development of network, the traditional vote method has already can''t satisfied people''s demanded. But in addition to completing traditional function, "the on-line vote system" has time limited efficacy more high and the scope wide advantage, meet the demand of modern society more.
The design of the on-line vote system with the dynamic password authentication scheme is a simple vote system have developed by ASP and SQL Server2000 technique, and established a dynamic verifiable code in the process of the customer login the system, enhanced system’s security. It can be effective implement the function of voting, examining, adding，deleting and searching votes. To start with, this thesis introduces the basic concept and the appliance scope of the on-line vote system. After that, the thesis make detailed introduction to the basic concept of the ASP, the SQL and the dynamic password authentication scheme in the part of the development environment of the system. Then it elucidates the creation of the database by the E-R diagram and the design of the database. Introduced the total design of this system immediately after, include: the system structure designs and the total function design. With the form of the function diagram, thesis explained the design of function, showed core code and the system circulate interface of the main function.

Key words: The on-line vote system; ASP; SQL; The dynamic verifiable code
