ECC-EXONUM-eVOTING: A Novel Signature-Based e-Voting Scheme Using Blockchain and Zero Knowledge Property

Abstract

Traditional voting systems mainly comprise of paper polling, electronic ballot system (EVM), mechanical devices, etc., and demand the physical presence of the voters. In the new age of digitization, the electronic voting system has come up with a unique facility to cast votes from any discreet place. However, the e-voting system has to face several challenges regarding security and privacy. To overcome such obstructions, blockchain is introduced in e-voting applications that preserve anonymity, security, and consistency of voter-related information with the help of Merkle tree and hash digest. Hence, any discrepancy can immediately be detected whenever the hash values of the respective block have been modified and consequently, the whole block is discarded. In this research, a novel e-voting scheme is proposed following the decentralized service-oriented architecture of Exonum private blockchain, hybrid consensus algorithm, and Elliptic Curve Diffie-Helmen (ECDH) protocol to agree upon a secure session key among different participants. Moreover, the proposed scheme (ECC-EXONUM-eVOTING) employs a zero-knowledge protocol and is customized to work over idemix technologies with a blind signature scheme. Numerous well-known cryptographic attacks are analyzed formally using the probabilistic random oracle model and informally for validating the security strength of ECC-EXONUM-eVOTING. As a result, it is found that the proposed scheme is well-defended against all potential security concerns. Furthermore, the scheme is simulated using both Automated Validation of Internet Security Protocols and Applications (AVISPA) and Scyther tools to demonstrate the proposed scheme is not prone to any security attacks. Finally, it is concluded that the proposed scheme is well-suited for secure e-voting applications.INDEX TERMS Distributed Ledger Technology (DLT), Elliptic Curve Discrete Logarithm Problem (ECDLP), Practical Byzantine Fault Tolerant (PBFT).

Analysis of research on the implementation of Blockchain technologies in regional electoral processes

“…In 2015, the internet was primarily a platform for information and communication for Czechs 93% of internet users use it for email communication, half of people use social networks, and 2/3 consume news portals. Czechs also frequently use the internet to search for information about goods and services and to make purchases [22].…”

“…In this section, we analyze the session key security of the proposed protocol using the ROR model [9]. We utlize the security model in Section 3.5 and follow the security proof of [34][35][36] which proved the session key security using the ROR model. Theorem 1.…”
