| 摘 要： | 针对当前存在的投票协议普遍要求一个可信赖的管理机构的问题，提出一种新的投票协议。该协议综合运用同态加密、门限密码体制、盲签名、环签名、零知识证明等密码技术，在假设无人弃权或虽有人弃权但管理者不与其他投票人合谋作弊的情况下，消除了无可信第三方和健壮性共存的矛盾，同时满足了匿名性、合法性、健壮性、可验证性和无可信第三方等安全属性。

| Abstract: | A new voting protocol was proposed to solve the problem that most of the existing voting protocols require a trusted management authority. This protocol comprehensively makes use of homomorphic encryption, threshold cryptography, blind signature, ring signature, zero knowledge proof, and so on, to resolves the coexistence problem between robustness and the absence of trusted third party under the assumption that no one abstains from voting or the authority does not cheat conspiracy with other voters when one voter abstains from voting, at the same time, anonymity, eligibility, robustness, verifiability and no trusted third party are also satisfied. |

| Keywords: | voting protocol threshold cryptosystem homomorphic encryption robustness no trusted third party |
