摘要

The security of electronic voting systems is an essential factor restricting its development. This paper proposes an electronic voting scheme based on LUC secret system and secret sharing. This scheme uses LUC to verify and identify voters' identities. Furthermore, it adopts Shamir's secret sharing to divide votes into multiple secret sharings, which are shared with all vote counters. The vote counters use the homomorphism of secret sharing to perform additional operations on the secret sharings received and then recover the final result of the voting. The proposed scheme meets the security requirements of anonymity, no receipt, verifiability and fairness, and so on. At the same time, it can obtain the final result without restoring the vote of each voter and there is an optimum number of vote counters, which guarantees the efficiency of the voting process. At last, it performs the voting process hierarchically. These advantages make our method suitable for electronic voting of different scales.
