Quantum block chain network anonymous election method and system based on trust evaluation

Abstract

The invention belongs to the technical field of quantum block chains. The invention discloses a quantum block chain network anonymous election method and system based on trust evaluation. The method comprises the following steps: identity trust evaluation of voters among miner nodes is completed by using a quantum secure direct communication technology, then voters calculate commitment values of voter election contents by using a quantum bit commitment protocol, and broadcast the commitment values to all miner nodes in a block chain; and then the miner nodes are combined with a quantum honestyByzantine protocol to complete voting statistics. The security model analysis of the protocol proves that the protocol has the advantages of anonymity, tamper resistance, verifiability and the like;according to the invention, the honesty quantum Byzantine protocol is adopted, so that the blockchain system can achieve a consistency protocol, and the protocol efficiency is better.

Description

technical field [0001] The invention belongs to the technical field of quantum blockchain, and in particular relates to a method and system for anonymous election of quantum blockchain network based on trust evaluation. Background technique [0002] Currently, the closest prior art: [0003] In recent years, the digital encryption currency system represented by Bitcoin has developed very rapidly. As the core supporting technology of digital encryption currency, blockchain technology has been widely concerned by scholars. Blockchain technology can effectively solve two major problems faced by traditional digital currencies, namely, the Byzantine generals problem and the double payment problem. Blockchain technology uses data encryption and time stamp technology to strictly ensure data security, and at the same time creatively adds means such as distributed consensus and economic incentives, and realizes point-to-point transactions of decentralized credit in a distributed net...

AI Technical Summary

Problems solved by technology

Furthermore, in the blockchain, the participation and withdrawal of nodes in an equal network composed of multiple central nodes are limited to a certain extent.

[0009] (2) The existing technology does not fully consider the problem of the range of honest nodes, and most of them use the traditional Byzantine agreement, so that when the blockchain system reaches consistency, the effective range of the algorithm is 0<p<1, which will cause block The consensus process of the chain system uses more resources and takes more time

[0010] (3) Most of the existing anonymous voting protocols do not meet all the requirements of the anonymous protocol: anonymity, verifiability, tamper-proof, etc.

How to achieve trust evaluation without adding too much cost to the voting system is a relatively difficult task

[0013] There are many ways to realize the Byzantine agreement in the traditional blockchain network, and the range of nodes to reach the consensus algorithm is relatively large, which is not conducive to the realization of the Byzantine agreement in the quantum communication network system.

[0014] (2) The three main characteristics of the anonymous voting protocol should all be satisfied. However, most of the existing protocols do not have the conditions to realize the three main characteristics
