Confidentiality Preserving Instant Runoff Voting System

Abstract

Voting is a mandatory application in any democratic country for decision making. The E-voting gives the promise or confidence of giving or delivering a convenient, straight forward and economical results. E-Voting system used many cryptographic methods to reduce the security problems in the election process. Voting is one of the essential activity which is used in various applications from student’s secretory elections, reality television shows, to national elections. With the goal of better efficiency, scalability, speed and lower cost, voting is currently changed from paper based to the use of electronic medium. This is targeted to meet better security, such that voting result gives true opinion of the voters. As of late in cryptography a few changes enable us to run troublesome calculations inside the encoded area. In democratic countries like India, Instant Runoff voting method is used in election of the President of India. In IRV, voter can vote by ranking the candidates in order of preference. To protect voter’s privacy, encryption is mostly used to ensure security in open network such as the internet. The cryptosystem based on Elliptic curve cryptography (ECC) is becoming the latest technology of public key cryptography. In proposed E-voting system, voter’s confidentiality is maintained by ECC, blind signature is used for ballot anonymity and authentication. This proposed scheme will effectively ensure confidentiality, anonymity and integrity of ballot in instant runoff voting method.
