Certificateless signature method based on elliptic curve discrete logarithm problem

Abstract

The invention discloses an efficient certificateless signature method based on an elliptic curve discrete logarithm problem. The method has the advantages of a common certificateless signature algorithm, namely a certificate management problem of a traditional public key system and a key escrow problem in an identity password system are eliminated; and the algorithm is simple in calculation process, and time-consuming bilinear operation does not need to use. The algorithm can be efficiently applied to fields such as e-commerce and the like of requiring the electronic signature.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a certificateless signature method based on an elliptic curve discrete logarithm problem. Background technique [0002] At present, network applications such as e-commerce are becoming more and more popular, which has greatly changed people's way of life. Although these applications have brought great convenience to people, their inherent security threats require us to seriously address them, otherwise these applications will only be passing clouds. [0003] Among all the security issues that need to be considered, the integrity of the data sent by the user and the authentication of the authenticity of the user's identity are one of the most basic issues. The solution to this problem requires the use of secure digital signature algorithms. Digital signature algorithms are generally implemented using public key cryptography. Due to the problems of certi...
