DABSTERS: Distributed Authorities using Blind Signature To Effect Robust Security in e-voting

Abstract : Creating an online electronic voting system that meets all legal requirements of election organizers and voters has constituted a real challenge for a long period of time. Permissioned Blockchains (also called Private Blockchains) are a cutting-edge invention, introduced as a security breakthrough for many existing and emerging technologies. One potential application of private Blockchain concerns e-voting systems. We propose a fully-decentralized e-voting system based on permissioned Blockchain, called DABSTERS in e-voting. Our system uses a blinded signature consensus algorithm, which is a modified version of Practical Byzantine Fault Tolerance (PBFT), to preserve voter's privacy. Our protocol ensures several security properties: voter's eligibility , vote integrity, vote secrecy, fairness, receipt freeness, individual and universal verifiability.
