Problems solved by technology

The existing revocation process is that the user calls or sends an E-mail to the administrator of the certificate authority CA, and the administrator manually revokes the user's digital certificate; when the administrator of the certificate authority CA fails to answer the user in time for some reason When revoking phone calls or emails, the digital certificates that need to be revoked cannot be revoked immediately, which will cause network security risks

Embodiment 1

[0045] The processing flow chart of the digital certificate revocation method provided by the embodiment of the present invention is as follows: figure 1 As shown, it is applied to the terminal entity of PKI technology, including:

[0046] Step S101: Obtain a digital certificate revocation instruction.

[0047] In this embodiment, the digital revocation instruction may be obtained when the user needs to revoke his digital certificate due to changes in user identity, user information, or user public key, user private key leakage, or user service suspension. A digital certificate revocation instruction sent by a user; it may also be a digital certificate revocation instruction automatically generated after a network device as an end entity detects an attack.

[0048] Step S102: Construct a digital certificate revocation request message according to the digital certificate revocation instruction.

[0049] When the terminal entity receives the digital certificate revocation inst...

Embodiment 2

[0074] exist figure 1 On the basis of the method shown, when the digital certificate revocation request message is sent to the certificate server, optionally, it also includes waiting for the certificate server to respond to the digital certificate revocation request message, such as image 3 As shown, including steps S101-S107, wherein:

[0075] Step 101-step 104 are the same as those in Embodiment 1, and will not be repeated here.

[0076] Step S105: Waiting to receive the digital certificate revocation response message responded by the server in the certificate authority, and start timing from the time when the digital certificate revocation request message is sent to the certificate server;

[0077] After the digital certificate revocation request message is sent to the certificate server, start timing from the time point when the digital certificate revocation request message is sent out, and record the time from sending the digital certificate revocation request message...

Embodiment 3

[0087] The embodiment of the present invention provides a digital certificate revocation device corresponding to the digital certificate revocation request message shown in Embodiment 1, and its structural diagram is as follows Figure 5 shown, including:

[0088] An acquisition unit 301, a processor 302, an encoder 303 and a transmitter 304;

[0089] in:

[0090] The acquiring unit 301 is configured to acquire a digital certificate revocation instruction;

[0091] The processor 302 is configured to construct a digital certificate revocation request message according to the digital certificate revocation instruction;

[0092] The encoder 303 is configured to digitally encrypt the digital certificate revocation request message and set an identity for the digitally encrypted digital certificate revocation request message;

[0093] The transmitter 304 is configured to send the digitally encrypted certificate revocation request message set with the identity mark to the certific...

Abstract

The invention discloses a digital certificate revocation method. The method comprises the following steps: obtaining a digital certificate revocation command by a client side; constructing a digital certificate revocation request message according to the digital certificate revocation command; carrying out digital encryption on the digital certificate revocation request message, and setting identity identification for the digital certificate revocation request message after digital encryption; and sending the encrypted digital certificate revocation request message with the identity identification to a certificate server so as to request the certificate server to perform digital certificate revocation. In the digital certificate revocation method, after the digital certificate revocation command input by a user is received, the digital certificate revocation request message is constructed and sent to the certificate server so as to perform digital certificate revocation so that the revocation process is more direct and faster, which ensures timeliness for digital certificate revocation and improves the safety of user information.

Description

technical field [0001] This application relates to the field of network security, in particular to a digital certificate revocation method and equipment. Background technique [0002] With the development of information technology and the improvement of people's quality of life, network technology has become a part of people's life, such as online banking and personal mailboxes that people often use in daily life. Network technology has changed people's lives more and more. At the same time, the communication security of network technology has attracted more and more attention. Most of the existing communication security guarantees for network technology use PKI technology. [0003] Public key infrastructure (English: Public Key Infrastructure, referred to as: PKI) is a system that provides system information security services through public key technology and digital certificates, and is responsible for verifying the identity of digital certificate holders. The PKI infrast...
