Sharing Responsibilities through Distributed Key Generation in the Chirotonia e-Voting Framework

Electronic voting systems are the subject of this paper. In particular, we focus on the Chirotonia platform, a secure and scalable voting framework based on blockchain and linkable ring signatures. One of the missing points of Chirotonia concerns the ownership of Confidentiality and in particular the use of a mechanism that allows to manage, in a distributed manner, the generation of the cryptographic material necessary to encrypt and decrypt ballots during and at the end of the voting process. The integration of a protocol for the distributed generation of cryptographic keys within the relevant web administration portal is hence appropriate. We will present in the paper a blockchain-based approach for the seamless integration of such a protocol inside Chirotonia.
