Verifiable post-quantum electronic voting system and implementation method therefor

摘要

Disclosed are a verifiable post-quantum electronic voting system and an implementation method therefor. The system comprises an authentication center, a user side, a verification server, a vote counting server, a verification program, and a bulletin board; the authentication center verifies the identity of a user, generates an identity ID for each valid user, and signs the identity ID; the user side verifies the identity of the user to the authentication center, receives signature of the identity ID, encrypts a vote of the user, and signs vote ciphertext and the identity ID and sends same to the verification server; the verification server comprises two servers, and the two servers jointly complete the verification of the validity of the vote and homomorphic vote counting; the vote counting server decrypts part of homomorphic vote counting ciphertext and issues same to the bulletin board; the verification program verifies whether the vote counting server correctly counts the votes. By means of the system and the implementation method therefor in the present invention, attack of a quantum computer can be effectively resisted, and high operation efficiency is realized.
