Abstract:
In this paper we present a fair e-voting protocol able to guarantee voter’s anonymity and double vote detection. The main cryptographic building blocks used by our system are two, namely, pairing-based blind signatures and elliptic curve digital signatures. We give both, a security and a cryptographic cost analysis of our proposed protocol, showing that it has a computational cost similar to other e-voting schemes previously reported, and the same time, it provides a good robustness against the potential attacks analyzed in this paper.
