Brief Announcement: Secure and Efficient Participant Authentication-Application to Mobile E-Voting

With Popularity of smart phones, more and more users tend to use them in e-voting activities. However, mobile devices has weak computing power and sometimes cannot support costly cryptographic operations. Vote validity proof is usually an inefficient ZK proof for the prover and liable to have poor performance on mobile devices. To overcome the bottleneck for mobile voters, an efficient protocol is proposed in this paper.
