A Secure Electronic Voting Based On Linkable Ring Signature

Electronic voting employs computer and network technologies to realize the voting function,which is based on cryptography.Voting administrator don't have to provide a large number of artificial ballots or carry on the work of counting the ballots and voters don't have to go to the regular voting center.Comparing with the traditional voting mode,electronic voting is more impartial,more secure,more efficient and more flexible, which can reduce man-made factors greatly.Furthermore,cryptography theory and application involving in electronic voting can be used for reference to the other aspects of electronic security fields.Therefore,it is significance to the study of electronic voting.And how to use the advantage of electronic voting thereby designs a more secure and more applicable electronic voting is also a hot issue in the security field.The main results and contents are as follows.1.Introduced a number of electronic voting Cryptography Theory,and Secure evoting should be introduced with a few basic properties.Then a representative of some electronic voting security program to conduct in-depth analysis.Found that certain existing security program of the existence of electronic voting security and operational deficiencies.2.In this paper,a ring based on the identity of the signature chain to achieve a secure electronic voting program.The program achieved the status of the anonymity of voters,democracy,integrity,accuracy,fairness and verifiability.The key lies in the program to solve the electronic voting program management center or the right group of managers resulted in excessive leakage of the question of the identity of voters,Voters can maintain the identity of unconditional anonymity.Second,the use of the signature chain ring allows the program to simplify the process,greatly improving the efficiency, Central and the nature of the signature itself to ensure the anonymity of the identity of voters.Third,the voters do not have to abstain from a vote Blank ballots,a person posing as voters can not vote.Furthermore,in view of the election,we might regret their vote,we can use ring signatures can be linked,and a new round of voting,the ballot papers with a new alternative to the old,so he will not because of negligence and hesitation and Cast votes in the wrong.
