| 摘要: |
| 提出了把动态多密门限体制应用于大规模选举的电子投票系统,它可以允许系统中存在多个监票人(机构).即使在选票的生成、加密、传输及解密、统计过程中存在自适应敌手,也不影响选举的正常进行,因此具有强壮性.提供的电子投票方案,无须调用多次交互式的零知识证明验证投票人的选举资格和监票人的身份,而是利用动态多密门体制方便地实现了选票的秘密性、广泛可验证性、公平性和匿名性,较之以前的投票方案具有较高的通信效率和安全性. |

| Abstract: |
| A dynamic multi-secrets sharing threshold scheme is presented to apply to a large scale electronic voting system with many talliers (tallying authorities). Even if there exist adaptive adversaries, this scheme can guard the ballot’s producing, encrypting, transmitting, decrypting and final tallying in spite of the adversaries’s attack, so the scheme guarantees robustness. In this paper, the verifiability of the voters’ qualification and talliers’ identification will be solved by a dynamic multi-secret sharing scheme without invoking more zero knowledge proof to maintain privacy, universal verifiablitlity, and anonymity of ballots. It holds more communication efficiency and more security than the proposed schemes in early time. |
