Targeting at some problems such as the control of a single authority and guarantee of privacy of multi-authority, this paper proposes a double-blind multi-authority e-voting system based Ghadafi’s group blind signature and SP-signature. By introducing multi-authority, this paper solves the control problem of a single authority. By using the SP-signature, voters cannot vote for others. The new system voter can protect confidentiality of voting information and the privacy of authority. Finally, the security of the new e-voting system is analyzed which includes eligibility, privacy, universal verifiability, uncoercibility, unreusability and fairness.
