Embodiment Construction

[0023] Such as figure 1 As shown, the present invention constructs an electronic voting protocol with n voters and m candidates. The present invention thus comprises the following steps:

[0024] 1. System initialization:

[0025] The voting management terminal sets the project name, voting questions and options, etc.; sets the start and end time points, including registration start time, registration end time, voting start time and voting end time; after the parameter setting is completed and released, voters will be notified that they can Start registration and enter the registration stage.

[0026] 2. Registration stage:

[0027] The registration is applied by the voter, and the private key is generated and the public key is calculated according to the digital signature algorithm based on the elliptic curve. A voter can become a legal voter only after submitting the public key and personal information; the list of legal voters will be written into the list of voters. T...

Abstract

The invention discloses an electronic voting method based on block chain and homomorphic time lock puzzle. The invention utilizes the homomorphic characteristics of the time lock puzzle to solve the problems that the existing electronic voting method based on the time lock puzzle does not support a large number of voters, the calculation of the puzzle takes a long time, and the problem of low efficiency makes electronic voting The system supports a large number of voters while canceling commitments, achieving stronger privacy protection and reducing computational overhead. The invention also utilizes the incentive mechanism of the block chain to encourage more people to participate in voting, so that the voting is more fair.

Description

technical field [0001] The invention relates to the fields of information security technology and electronic voting technology, and relates to an electronic voting method based on block chains and homomorphic time lock puzzles. Background technique [0002] In recent years, electronic voting has attracted great attention because it can greatly improve the efficiency of voting activities and the accuracy of results. Security issues have always been the bottleneck restricting the development of electronic voting. Therefore, it is very necessary to study the security of electronic voting and design an electronic voting scheme that protects privacy. [0003] Existing electronic voting methods based on time-lock puzzles do not support a large number of voters, computing puzzles takes a long time, are inefficient, do not consider incentive mechanisms, and lack credible authorities, which limit the use of time-lock puzzles in electronic voting. field applications. In addition, th...
