ABSTRACT:
A voter Viencrypts his vote content viwith a public key kPCof a counter C, then concatenates the encrypted vote content xiwith a tag tito obtain a ballot zi, then randomizes it with a random number rito create a preprocessed text ei, and sends it and a signature sitherefor to an election administrator A. The administrator A generates a blind signature difor the preprocessed text eiand sends it back to the voter Vi. The voter Viexcludes the influence of the random number rifrom the blind signature dito obtain administrator signature yi, and sends vote data <zi, yi> to a counter C. The counter C verifies the validity of the administrator signature yiand, if valid, generates and publishes a vote list containing the data <zi, yi> to the voter Vi. The voter Vichecks the vote list to make sure that it contains the data <zi, yi> with his tag tiheld in the ballot zi. The counter C decrypts the encrypted vote content xiin the ballot zito obtain the vote content vi, and counts the number of votes polled for each candidate.
