报告摘要：A challenging task in the design of secure e-voting system is that a voter could verify whether his vote is recorded and counted correctly, while he has no evidence to prove his ballot in order to prevent a malicious voter from selling his vote. Bingo Voting scheme has been proposed to achieve the verifiability and coercion-resistance; however, it has a weakness, which could still lead to vote selling due to a potential of side channel attack. A malicious voter could take a picture of the fresh random number displayed in the voting booth using a secret camera, and then prove to others which candidate he has selected. In this paper, we propose an improved voting scheme, which does not require a trusted random number generator and eliminates the side channel attack, while our scheme still retains the properties of verifiability and coercion-resistance. It also allows the voter to check whether the receipt is correct even after he has left the voting booth.
