Go-Ethereum for electronic voting system using clique as proof-of-authority

Current advances in information technology have brought about significant changes, including ways to carry out elections using computer technology known as e-voting. Blockchain underlies the popularity of the digital currency Bitcoin and some other digital money, sparking the start of a new era of Internet use, including electronic voting (e-voting) system. In this work, we proposed designing and implementing an evoting system powered by the Ethereum blockchain. We used real-world data from the Indonesian Election Commission (KPU) with 26 candidates and 15,725 voters from the Jelupang sub-district. The testing and evaluation results using three miners in the blockchain show that the system could commit around 23 transactions per second. All 15,725 votes are committed to the blockchain successfully within 12.75 minutes. The total time required for creating all blockchain accounts is 13.4 hours.

TRVote: A New, Trustworthy and Robust Electronic Voting System

We propose a new Direct-Recording Electronic (DRE)-based voting system that we call TRVote. The reliability of TRVote is ensured during the vote generation phase where the random challenges are generated by the voters instead of utilizing the random number generator of the machine. Namely, the challenges of voters are utilized to prevent and detect a malicious behavior of a corrupted voting machine. Due to the unpredictability of the challenges, the voting machine cannot cheat voters without being detected. TRVote provides two kinds of verification; cast-as-intended is ensured during the vote generation phase and recorded-as-cast is ensured through a secure Web Bulletin Board (WBB). More concretely, voters can verify that their votes are cast as intended via a zero-knowledge proof on a printed receipt using QR codes. After the election, the central server broadcasts all receipts in a secure WBB where the voters (or, perhaps proxies) can check whether their receipts appear correctly. In order to implement the voting process, the proposed voting machine has simple components such as mechanical switches, a touchscreen, and a printer. In this system, each candidate is represented by a mechanical switch which is equipped within the voting machine. The machine has a flexible structure in the sense that the mechanical switches can be placed and removed as plug-ins depending on the number of candidates which allows to support arbitrary number of candidates. We show that the proposed system is robust and guarantees privacy of voters. We further analyze that it is universally verifiable and secure against coercion

Electronic voting : 6th International Joint Conference, E-Vote-ID 2021, virtual event, October 5-8, 2021

This book constitutes the proceedings of the 6th International Conference on Electronic Voting, E-Vote-ID 2021, held online -due to COVID -19- in Bregenz, Austria, in October 2021. The 14 full papers presented were carefully reviewed and selected from 55 submissions. The conference collected the most relevant debates on the development of Electronic Voting, from aspects relating to security and usability through to practical experiences and applications of voting systems, as well as legal, social or political aspects

Sixth International Joint Conference on Electronic Voting E-Vote-ID 2021. 5-8 October 2021

This volume contains papers presented at E-Vote-ID 2021, the Sixth International Joint Conference on Electronic Voting, held during October 5-8, 2021. Due to the extraordinary situation provoked by Covid-19 Pandemic, the conference is held online for second consecutive edition, instead of in the traditional venue in Bregenz, Austria. E-Vote-ID Conference resulted from the merging of EVOTE and Vote-ID and counting up to 17 years since the _rst E-Vote conference in Austria. Since that conference in 2004, over 1000 experts have attended the venue, including scholars, practitioners, authorities, electoral managers, vendors, and PhD Students. The conference collected the most relevant debates on the development of Electronic Voting, from aspects relating to security and usability through to practical experiences and applications of voting systems, also including legal, social or political aspects, amongst others; turning out to be an important global referent in relation to this issue. Also, this year, the conference consisted of: · Security, Usability and Technical Issues Track · Administrative, Legal, Political and Social Issues Track · Election and Practical Experiences Track · PhD Colloquium, Poster and Demo Session on the day before the conference E-VOTE-ID 2021 received 49 submissions, being, each of them, reviewed by 3 to 5 program committee members, using a double blind review process. As a result, 27 papers were accepted for its presentation in the conference. The selected papers cover a wide range of topics connected with electronic voting, including experiences and revisions of the real uses of E-voting systems and corresponding processes in elections. We would also like to thank the German Informatics Society (Gesellschaft für Informatik) with its ECOM working group and KASTEL for their partnership over many years. Further we would like to thank the Swiss Federal Chancellery and the Regional Government of Vorarlberg for their kind support. EVote- ID 2021 conference is kindly supported through European Union's Horizon 2020 projects ECEPS (grant agreement 857622) and mGov4EU (grant agreement 959072). Special thanks go to the members of the international program committee for their hard work in reviewing, discussing, and shepherding papers. They ensured the high quality of these proceedings with their knowledge and experience

Clash attacks and the STAR-Vote system

STAR-Vote is an end-to-end cryptographic voting system that produces both plaintext paper ballots and encrypted electronic records of each ballot. We describe how clash attacks against STAR-Vote could weaken its security guarantees: corrupt voting terminals could identify voters with identical ballot preferences and print identical receipts for them, while generating electronic ballot ciphertexts for other candidates. Each voter would then be able to \verify" their ballot on the public bulletin board, but the electronic tally would include alternative ciphertexts corresponding to the duplicate voters. We describe how this threat can be exploited and mitigated with existing STAR-Vote mechanisms, including STAR-Vote's use of Benaloh challenges and a cryptographic hash chain. We also describe how this threat can be mitigated through statistical sampling of the printed paper ballots as an extension to the risk-limiting audits that STAR-Vote already requires
