A New Cryptographic Voting Verifiable Scheme for E-Voting System Based on Bit Commitment and Blind Signature

摘要

The main challenge in electronic voting (EV) systems is the security issue which has gained an interest of researchers in the last twenty years. EV system is one of the most important Internet-related activities. Recently many countries moved to electronic voting instead of a traditional one for many reason. Electronic voting has been studied for over the last twenty years. Until now, many EV schemes have been proposed. However, there is no a complete solution in both theoretical and practical areas. So, the researchers try to preserve the cryptographic primitives to build e-voting schemes with high efficiency to achieve these requirements. In this paper, we present a new cryptographic verifiable voting system. The digital signature represents one of the most important applications of cryptographic protocols In order to implement the cryptographic protocols in the field EV systems, it is important to secure the communication channels to the legal users. Therefore, the main target of this paper is to design a scheme which is more effective and achieving higher security properties based on bit commitment infrastructure and digital signature technology. In this system, the improper behavior of the voter will be detected and invalid or double votes will not be taken into account. In addition, the voter has the ability to prove that his vote is in correct form without disclosing any other information about his vote and his decision.
