Weaknesses in the Moscow Internet Voting System

Explore the vulnerabilities in Moscow's Internet voting system through a detailed presentation given at the Workshop on Attacks in Cryptography (WAC) 2020. Delve into the context of the election, the public testing process, and the timeline of events in Summer 2019. Examine the triple-ElGamal encryption method used and the first attack involving solving the Discrete Logarithm Problem (DLP). Analyze the subsequent encryption fix and its effectiveness. Gain insights into the protocol overview, the role of encryption, and additional observations. Assess the impact of the findings on nationwide voting for constitutional amendments. Evaluate the system's usage and reported issues before drawing conclusions about the security and integrity of Moscow's Internet voting infrastructure.
