Abstract:	近期電子投票系統被廣泛討論，許多國家也開始實行電子投票系統來取代傳統紙本投票。而一套完整的電子投票系統欲取代傳統紙本投票，此系統就必須滿足傳統紙本投票的需求，有完善的機制用以保護投票者在進行投票時的隱私性，保證投票者的身分及選票內容不被其他人得知，並維持整個投票過程的完整性、可驗證性及公平性等等的需求，系統的穩定性也是必須要考量的因素。本篇論文主要針對投票者的隱私性及如何減輕投票者的負擔進行討論，我們提出了參考愛沙尼亞國家的電子投票系統的優點做結合，設計出一個改良的基於模糊簽章的電子投票系統。 Electronic voting systems have been widely investigated in recent years since they are very convenient for voters. Many countries have begun to implement electronic voting system to replace the traditional voting system. In order to replace the traditional voting system, an e-voting system must satisfy all the security requirements of those in a traditional voting system. Those security requirements are, firstly, to have a sound mechanism to protect a voter’s privacy, and to ensure that the identity of a voter or the content of a ballot will not be leaked to others. Moreover, it must maintain the integrity, verifiability and fairness during the entire voting process. To keep the system stable during the voting process is also an important factor that must be considered. This thesis is a research on designing a secure electronic voting system. Based on some existing electronic voting systems, we design an improved system to enhance the privacy protection of voters on one hand and to reduce the loading of voters on the other hand. In detail, our scheme is modified from the existing e-voting system of Estonian state, and we proposed an improved e-voting system which uses the oblivious signatures as a building block.
