Decentralized quantum anonymous veto voting scheme based on measurement-device-independence

Abstract

To remove any trusted third party from the voting scheme, a new primitive quantum secure multiparty exclusive OR protocol based on Measurement-Device-Independence (MDI) is presented by utilizing entanglement swapping of Bell states. Based on this primitive protocol of quantum secure multiparty protocol, a novel quantum anonymous veto voting scheme is constructed, which can meet complete security attributes. Especially, this scheme does not need any third party to count the votes, while all voters can tally the voting results by themselves. At the same time, blockchain is introduced for supervision, so that the voters can verify the validity of the voting content under extreme circumstances. The voting scheme takes Bell states as quantum resources and only performs Bell states identification based on the principle of MDI, so it is feasible to implement this scheme with the present quantum information processing technologies. Finally, the proposed voting scheme is simulated in IBM Qiskit, and the simulation results show that this scheme is correct and feasible.

Implementing quantum anonymous multi-party ranking: the influence and application of the law of large numbers

“…Encouragingly, quantum protocols provide unconditional security in theory. Many researchers have designed various SMC schemes based on quantum mechanical principles, including quantum secret sharing (QSS) [10][11][12][13], quantum private query (QPQ) [14][15][16], quantum anonymous multi-party ranking (QAMR) [17][18][19][20], quantum secure multi-party summation (QSMS) [21,22], and among others [23][24][25][26][27][28]. In QAMR, each participant can obtain the ranking of his private data in ascending or descending order at the end of the protocol without revealing their private data.…”

Enhanced quantum secret sharing protocol for anonymous secure communication utilizing W states

“…Anonymous entanglement is the core of QASS, achieved by performing local operations at nodes in the network to create entanglement links between senders and anonymous receivers. It also plays a crucial role in protecting user identity anonymity in quantum cryptography, with many protocols proposed for various tasks such as anonymous ranking, 15 , 16 , 17 voting, 18 , 19 , 20 and communication. 21 , 22 , 23 Among these, GHZ states are the most commonly used anonymous entanglement resource.…”
