應用於群體決策的無記名投票系統

Abstract

隨著資訊科技的進步，透過電腦網路的連接，人們可以跨越時空限制 ，在一個虛擬的環境中進行討論或開會。但當進行某個議案表決時，投票 者會面臨到：個人意願在表達時的壓力，以致於無法完全表達自我意念， 使得投票的結果受到限制。 本論文實作出一個可以與群體決策相結合 的無記名投票系統，以便增進投票者勇於表達的意願。本論文所開發之投 票系統，採用的投票協定為模仿現行傳統紙張式的投票制度而發展出來的 。配合密碼學的應用，本論文之投票系統將能達成「可驗證」與「無記名 」的兩大投票特性。加上電子化的數位選票，能表達出傳統紙張選票所無 法展現的立體效果。使得在電腦網路上進行電子投票時，是在一個既方便 又安全又可靠的環境下，達成群體決策的最高品質。 In this thesis, we have developed an anonymous voting system that canbe applied to group decisions. People can convene a conference on computernetworks because of the development of information technology. But when theyneed to vote in the conference, they will have the same trouble to expressthemselves as face-to-face meeting. The electronic voting system we havedeveloped can provide an anonymous and verifiable voting enviroment by usingcryptographic instruments. The system can be applied to group decisions easilybecause it uses the conventional voting procedure. Now, people will have a convenient, secure, and reliable voting tool when they take a conference on computer networks.
