Embodiment Construction

[0017] specific implementation plan

[0018] After the start of step S101, after the user sends a request for digital certificate authentication in step S102, the judgment of NFC identity recognition at N1 is performed at step S103, and the user needs to produce a slave device identified by NFC distributed during certificate registration to prove identity Make close contact with the NFC master device, the master device obtains the NFC data format standard label in the slave device, and then encrypts the hash algorithm, and then the data is sent to the background to judge whether it has been authenticated; when it is detected that the database has no relevant identity information When the identification is successful, it will enter step S105, and a window of authentication failure will pop up, pointing out that the database does not compare the relevant digital certificate information; After the registered binding certificate is retrieved, obtain it locally in step S106. After ...

Abstract

The invention provides a digital certificate authentication method based on NFC identification, and the method comprises the following steps: carrying out NFC identification, carrying out Hash encryption on the identified information, transmitting the encrypted information to a background for comparison, comparing a bound digital certificate with a certificate of a user after successful comparison, and carrying out decryption by adopting an ECC algorithm of large integer decomposition, and under the condition of consistency, querying the CRL revoked certificate list, and when the state of the certificate is normal, completing the authentication of the digital certificate.

Description

technical field [0001] The invention relates to a digital certificate authentication method, on which NFC identification is added, and the digital certificate is characterized in that an ECC algorithm decomposed by a large integer is used for decryption, and SHA-256 is used for verification. Background technique [0002] Today, with the continuous development of science and technology, shopping on the Internet and financial transactions have become very normal, and this requires the security of personal information on the Internet to be guaranteed. Therefore, in this case, digital certificates were born, with strong Identity authentication solves security problems, but because of its indiscriminate authentication, it is impossible to verify the user's identity, and there are problems. Therefore, adding NFC short-distance communication technology on the basis of digital certificate authentication can To achieve identity authentication, users of digital certificates must be ap...
