Certificate false proof method based on light weight digital signature scheme

Abstract

The invention relates to a method for proofing false certificates based on a lightweight level digital signature scheme, which belongs to the cryptography and the computer field, the method enables the unforgeability of the certificates to be corresponding to the safety of a public key digital signature scheme and comprises the three parts of a key generating part of certificate forgery, a digital signature part and an identification checking part, wherein the key generating part is used for generating a pair of a private key and a public key of a license-issuing authority, the digital signature part is used for generating signature codes to the Hash abstract of key information of the certificates for the license-issuing authority, the identification checking part is used for identifying authenticity of the certificates for a user end inquiry unit, the method is safe and has low cost, can prevent insiders of the license-issuing authority commit a crime, can replace official seals of companies and can widely used in distributing business of various certificates.

Description

(1) Technical field [0001] A certificate anti-counterfeiting method based on a lightweight digital signature scheme belongs to the field of cryptography and computer technology, and is closely related to information security technology. (2) Background technology [0002] The digital signature scheme is a kind of public key cryptography technology, which can be used to sign data files in computers or on the Internet (Internet). The signature is non-repudiation and verifiable. [0003] The process is as follows. The user first obtains the Hash summary of the data file or message, and then uses his own private key to calculate the Hash summary to generate a signature code. Anyone can verify the signature code because the user's public key is public. When verifying, the verifier also first obtains the Hash summary of the same data file or message, and then uses the user's public key to calculate the Hash summary to see if the result satisfies a certain pre-set discriminant. ...

AI Technical Summary

Problems solved by technology

There are also forged behaviors such as car driver's licenses and real estate certificates, which have also caused great damage to social stability and the legitimate operation of the economy.

[0007] Current anti-counterfeiting methods, such as text and image comparison, physical methods, optical methods, etc., cannot fundamentally eliminate counterfeiting. Therefore, it is necessary to study new and more effective anti-counterfeiting methods
