PVPBC: Privacy- and Verifiability-Preserving E-Voting Based on Permissioned Blockchain

Privacy and verifiability are crucial security requirements in e-voting systems combining them is considered to be a challenge given that they seem contradictory. On one hand, privacy means cast votes cannot traced the corresponding voters. other linkability of voters their requirement which has consequence voter able check vote election result. These two contradictory features can addressed by adopting privacy-preserving cryptographic primitives, at same time as achieving privacy, achieve verifiability. Many end-to-end schemes support have need for some action. This makes ballot casting more complex We propose PVPBC voting system, an system preserves without affecting usability. The uses effective distributed method authorization, based on revocable anonymity, making use permissioned ledger smart contract. In addition, underlying satisfies using Selene scheme. protocol verifiable protocol. It publishes plaintext accompanied tracking numbers. enables confirm been captured correctly system. Numerical experiments claim scales well function number candidates. particular, PVPBC’s authorization increases linearly population size. average latency associated with accessing also incurred when valid authentication transaction created sent DLT network 6.275 ms. Empirical results suggest cost GBP storing encrypted alongside tracker commitment linear candidates, attractive aspect PVPBC.
