Multiple digital signature method based on identity cipher mechanism

Abstract

The invention relates to a multiple digital signature method based on an identity cipher mechanism. The method comprises the steps that 1 system parameters are initialized; 2 keys are generated and distributed; and 3 multiple signatures are generated and authenticated. According to the invention, the investment cost of an authentication mechanism can be reduced; the burden of certificate management is reduced; the operation efficiency of a system is improved; and the security and stability of the system are strengthened.

Description

technical field [0001] The invention relates to data security technology, in particular to a multiple digital signature method based on an identity password mechanism. Background technique [0002] Digital signature is one of the important issues in cryptography. It is the simulation of traditional document handwritten signature, which can realize the user's authentication of electronically stored messages. Digital signatures can provide data source authentication, data integrity, and non-repudiation. Usually, trusted certification authorities use digital signatures to sign certificates that bind communication entities with their public keys. In fields such as e-commerce and enterprise information platforms, the digital signature system is widely used. The security of digital signature is the key technology to guarantee authentication, authorization, integrity, non-repudiation and other security services. [0003] The goal of a digital signature is similar to a physical no...

AI Technical Summary

Problems solved by technology

[0005] 1. The cost and complexity of establishing such a certification body are very high, which requires a large investment by the certification body, which undoubtedly increases the burden of certificate management;

[0006] 2. The complexity of system calculation is high, which seriously reduces the calculation efficiency of the system;

[0007] 3. There is the possibility of internal collusion attacks. The verifier can only know the signature of the person in front of him and the authenticity of the signature, which affects the security and stability of the system;
