Problems solved by technology
[0008] The purpose of the present invention is to provide a controllable anonymous voting system based on blockchain and decentralized traceable attribute signature, and solve the problem of existing electronic voting by combining blockchain with decentralized traceable attribute signature technology. The authenticity of votes in the system cannot be guaranteed and the privacy of voters is leaked. While conducting controllable anonymous authentication of voters, the authenticity, validity and verifiability of votes are guaranteed.

Embodiment Construction
[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below according to specific embodiments and accompanying drawings, but the protection scope of the present invention is not limited to the following embodiments.
[0033] The workflow of the controllable anonymous voting system of the present invention is as follows: image 3 As shown, the specific workflow is:
[0034] (1) System initialization
[0035] GlobalSetup(λ)→PK: Initialize the basic parameters of the system, input the security parameter λ, and generate the public parameter PK;
[0036] RASetup(PK)→RPK,RSK,K base : Regulatory agency RA initializes and generates public key RPK, private key RSK and attribute private key base K base ;
[0037] (2) UGen(PK, baseinfo, RSK) → uid: User registration, input the public parameter PK, user basic information baseinfo and regulatory agency private key RSK, complete u...

The invention belongs to the field of electronic voting, and particularly relates to a controllable anonymous voting system based on a block chain and a decentration traceable attribute signature. The system comprises a controllable anonymous authentication module, a decentralized voting module, a user module and a block chain module. The controllable anonymous authentication module provides an anonymous authentication service for the user, generates an attribute private key, and recovers real identity information of the related user according to a signature when a dispute occurs in a voting result; the decentralized voting module is responsible for specific voting operations of users, including verification of validity of voting users and statistics of final voting results; the user module is responsible for maintaining related identity information of a user; and the block chain module is responsible for uploading specific data and ensuring the authenticity and non-tampering of the voting data. According to the method, the problems of voting authenticity and user privacy protection commonly existing in the existing electronic voting system are solved, and the identity privacy information of the user is protected to the greatest extent on the premise of ensuring that voting is true, effective and verifiable.
Description
technical field [0001] The invention belongs to the technical field of electronic voting, and in particular relates to a controllable anonymous voting system based on block chain and decentralized traceable attribute signature. Background technique [0002] With the continuous progress of the society and the rapid development of the economy, polling surveys have played an increasingly important role in social life. From the political work of the government to the investigation and development of enterprises, voting activities can be seen everywhere. However, there are various problems in the traditional offline voting method, which cannot keep up with the pace of social development: 1) Offline voting requires staff to participate in the organization, and space and time are limited; 2) Ballots for offline voting need to use a large number of Paper causes waste of resources; 3) Offline voting makes the post-vote counting process take a lot of time and energy, and manual count...
