Embodiment 1

[0124] figure 1 It is a flow chart of the method for generating a blank electronic certificate provided in the first embodiment of the present invention. The method for generating a blank electronic certificate provided in this embodiment is used to generate a blank electronic certificate, such as figure 1 As shown, the method includes:

[0125] Steps for generating blank electronic credential identification information (step 101 to step 103):

[0126] Step 101: Generate first electronic credential information based on at least the preset electronic credential face information, electronic credential issuer public key, and electronic credential issuer name;

[0127] The electronic voucher face information includes one or any combination of two or more of the following information:

[0128] Electronic certificate code, electronic certificate number, electronic certificate type, name of electronic certificate issuing authority, electronic certificate quota, electronic certifica...

Embodiment approach

[0155] The step 103 further includes: generating a blank electronic certificate together with the first electronic certificate information, the public key of the electronic certificate issuing authority, the signature of the issuing authority, and the public key of the electronic certificate issuer; the public key of the electronic certificate issuing authority is any authority The issued valid public key corresponding to the private key.

Abstract

The invention discloses blank electronic credential generation and blank electronic credential public verification methods, devices and system. The blank electronic credential generation method comprises the following steps: generating first electronic credential information at least according to electronic credential face information among preset electronic credential face information, the public key of an electronic credential accrediting party and the name of the electronic credential accrediting party; using a first signature algorithm and the private key of an electronic credential issuing authority to sign the first electronic credential information to get the signature of the issuing authority; and generating a blank electronic credential according to the first electronic credential information, the public key of the electronic credential issuing authority and the signature of the issuing authority. The anti-counterfeiting property of electronic credentials is enhanced. Mixed use and illegal use of electronic credentials can be prevented. The shortcomings of the prior art, for example, someone pretends to be the credential issuing authority to issue electronic credentials, electronic credentials are used in a mixed way between different electronic credential accrediting parties, and electronic credentials are used illegally, are avoided. The verification difficulty of electronic credentials is reduced. Verification of electronic credentials is easy.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a blank electronic certificate generation and public verification method, device and system.
