In order to solve the issues existing in the electronic voting, such as voter privacy disclosure, registration center deceive voters and ballot forgery, etc. A new electronic voting scheme based on the principle of eletronic voting and the technology of ring signature was proposed. In this scheme, the serialized and blinded ballots were deliverd to legal voters,and a voter can select other eligible voter’s public key to make up a virtual voting group, sign the ballot using a ring signature algorithm, and accomplish the voting task.
