An Identity-based Blind Signature Approach for E-voting System

Electronic voting is a voting process using electronic mean that allows voters to cast their secret and secure vote over an unsecured channel.Many forwardthinking countries are adopting the electronic voting system to upgrade their election process.Since E-voting system is more complex so it requires more security as compared to the postal voting system.One of the fine tool to provide the voter anonymity is the blind signature scheme.Many blind signature proposals based on traditional public key cryptosystem have been discussed, however, they get the worst of certificate and public key management.In this sense, the objective of the paper is twofold.Firstly, we proposed a blind signature scheme using the identity-based cryptosystem.Proposed scheme uses the combination of Bolyreva's blind signature scheme and Cha-Chaon's Identity-based signature.Secondly, we show that proposed scheme is more suitable for E-voting system as compared with others ID-based blind signature scheme.
