- ZKPs in Cryptographic Voting (Development)https://github.com/kantuni/ZKP
The main idea of this project was to present the notion of zero-knowledge proofs and their use in cryptographic voting. I started with the implementation of a primitive voting scheme called "mini-voting" that has few security issues. I then implemented a new scheme (a variant of the "helios" scheme) based on "mini-voting" that uses a concept of zero-knowledge proofs to solve these issues. I used two protocols that ensured zero knowledge: Chaum-Pedersen and DCP (Disjunctive Chaum-Pedersen).
