摘  要
隨著網絡技術的迅速發展，傳統的投票方式已經不能滿足人們的需要。而網上投票系統除了能夠完成傳統的功能之外，更具有時效高和范圍廣的優點，更符合現代社會的需要。
具有動態口令認證機制的網上投票系統的設計是采用ASP和SQL Server2000技術開發的簡易投票系統，并在用戶登陸過程中設置動態驗證碼，提高系統的安全性。它實現了以下功能:投票、結果查看、增加、刪除及搜索投票等。本論文首先介紹了網上投票系統的概念及和適用范圍。在系統開發環境中主要對ASP、SQL和動態口令認證機制的基本概念作了詳盡的介紹。接著通過E-R圖說明數據庫的搭建和數據庫的設計。然后介紹了本系統的總體設計，包括：系統結構和總體功能設計。論文以功能模塊圖的形式說明了功能的設計并給出了部分核心代碼及主要功能界面圖。

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
