A Cryptanalysis of Trustworthy Electronicvoting using Adjusted Blockchain Technology

The voting process and results and the trust of voters are very important issues in current modern society. When voters could trust that the voting results are valid, people are willing to trust this voter will serve for them dealing with issues such as national security, education, and economics in the future. Electronic voting is an efficient method that could help people who could not vote in a limited period. Besides, it also solves the problem of long voting time due to many voters or more complicated voting steps. Although the voting machine could perform a record of votes and voting calculations, it does not require humans to handle a lot of above voting works. Nowadays, electronic voting has become an important research. However, there are too many assumptions and institutions which are often added in this research area. It might become to be unpractical when this voting research is applied to real society. Hence, we thought that blockchain might be a good solution for electronic voting research. Nevertheless, how to apply blockchain to protect people's privacy, anonymity, and voting rights still needs to be discussed in current days. In this paper, we proposed cryptanalysis on a trustworthy electronic voting scheme with blockchain and find out that there are some problems in their proposed scheme.
