A Framework for e-Voting System Based on Blockchain and Distributed Ledger Technologies

Election allows the voter of a country to select the most suitable group of candidates to run the government.Election in Pakistan is simply paper-based method but some certain political and socio-economic issues turn that simple process in complicated and disputes once.Solutions of such problems are consisting of many methods including the e-voting system.The e-voting system facilitates the voters to cast their votes by electronic means with very easy and convenient way.This also allows maintaining the security and secrecy of the voter along with election process.Electronic voting reduces the human-involvement throughout the process from start to the end.Such system is not established yet in Pakistan.Hence,every election is disputed always.In this paper we proposed the framework of an e-voting system and simulation with the use of blockchain ledger technology.The proposed framework owns the capacity to deal with ballots in Pakistan.The novelty of the framework is that the e-voting system is linked to National Database and Registration Authority(NADRA)database which assures voter’s validation.The fundamental requirements were kept in consideration during the performance evaluation of the system.The results are processed and depicted specially with reference to the number of voters and voting stations,real time of vote casting,network bandwidth and controlling principles.The results support the decision makers and guide them in the foundation and customization of an e-voting system in Pakistan.

Securing a Scalable E-Voting System Using the RSA Algorithm: The Case of a Group Voting Process in a Tertiary School

E-voting (electronic voting) is a significant part of an E-election (electronic election), which refers to the use of computers or computerized voting equipment to cast ballots in an election. Due to the rapid growth of computer technologies and advances in cryptographic techniques, E-voting is now an applicable alternative for many non-governmental elections. However, security demands are paramount to electoral process in political arena. It was revealed that researchers show little interest in robustness of E-voting system compared to other E-voting requirements [1]. This paper shows that RSA (Ron Rivest, Adi Shamir and Leonard Adleman) cryptography algorithm can be incorporated into E-voting process as a whole. The RSA cryptography algorithm ensures that votes casted are secured, thus maintaining the privacy of votes. The performance of the cryptography algorithm is tested on a university E-voting system over a public network. The E-voting process is initiated by a server system that other computer nodes are connected to. The system is such that when the votes are cast on the nodes, the RSA technique encrypts the vote that is sent to the server system using both node and vote identity number. The system performs consistently and reliably which in return gives good level of confidence of votes count.

Development of a General-Purpose E-Voting Server

Voting is a general and indispensable method, and widely used to express a choice or preference, to elect a person, or to choose an opinion by ballot in education, enterprise, medicine, and government.?Until now, various E-voting schemes are proposed in the world but they are different from each other. There is no system that can provide users with E-voting services anytime and anywhere such that one can use E-voting servers without even thinking about them.?Therefore, an E-voting system for general-purpose is demanded. To support any kinds of vote, we divide voting system into components, and make different assembly of those components for different kinds of voting.

E-voting system using cloud-based hybrid blockchain technology

With the invention of Internet-enabled devices,cloud and blockchain-based technologies,an online voting system can smoothly carry out election processes.During pandemic situations,citizens tend to develop panic about mass gatherings,which may influence the decrease in the number of votes.This urges a reliable,flexible,transparent,secure,and cost-effective voting system.The proposed online voting system using cloud-based hybrid blockchain technology eradicates the flaws that persist in the existing voting system,and it is carried out in three phases:the registration phase,vote casting phase and vote counting phase.A timestamp-based authentication protocol with digital signature validates voters and candidates during the registration and vote casting phases.Using smart contracts,third-party interventions are eliminated,and the transactions are secured in the blockchain network.Finally,to provide accurate voting results,the practical Byzantine fault tolerance(PBFT)consensus mechanism is adopted to ensure that the vote has not been modified or corrupted.Hence,the overall performance of the proposed system is significantly better than that of the existing system.Further performance was analyzed based on authentication delay,vote alteration,response time,and latency.

End-to-end verifiable electronic voting scheme of blockchain based on random linear block code

Blockchain is an emerging decentralized technology of electronic voting.The current main consensus protocols are not flexible enough to manage the distributed blockchain nodes to achieve high efficiency of consensus.For practical implementation,the consensus based on random linear block code(RLBC)is proposed and applied to blockchain voting scheme.Along with achieving the record correctness and consistency among all nodes,the consensus method indicates the active and inactive consensus nodes.This ability can assist the management of consensus nodes and restrain the generating of chain forks.To achieve end-to-end verifiability,cast-or-audit and randomized partial checking(RPC)are used in the proposed scheme.The voter can verify the high probability of correctness in ballot encryption and decryption.The experiments illustrate that the efficiency of proposed consensus is suitable for blockchain.The proposed electronic voting scheme is adapted to practical implementation of voting.
