Embodiment Construction
[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0022] The invention provides a method for inquiring user public key certificates between application systems based on the PKI system, and the method is implemented based on a local area network or a private network application system of the PKI system.
[0023] The application systems involved are all based on the PKI system, and all application systems can communicate with each other.
[0024] Each application system will form user unique identification information for registered users, each user has a corresponding certificate, and each certificate has a unique identification item value. The user unique identification information in the application system may include character information contained in the GBK character set, but is not limited...

The invention discloses a method for querying public key certificates of users between PKI (public key infrastructure)-system-based application systems. The method comprises the following steps of the application system A obtains a unique certificate identification item value of a user B1 according to the unique user identification information of the user B1 through external data acquisition service provided by the application system B, acquires certificate storage server configuration information corresponding to the application system B through the external data acquisition service provided by the application system B, and finds a signed public key certificate or an encrypted public key certificate of the user B1 in a certificate server by utilizing the acquired unique certificate identification item value of the user B1. According to the method, the conventional system is slightly changed, and the public key certificates of the users can be queried among a plurality of application systems.
Description
technical field [0001] The invention belongs to the technical field of computer and information security, and specifically relates to a user public key certificate query method between local area network or private network application systems based on the PKI system. Background technique [0002] As people's awareness of application system security increases, there are more and more application systems based on the PKI system, and the demand for mutual integration between application systems based on the PKI system also arises. In the application systems based on the PKI system, many business processes There will always be a need for business data to be encrypted, signed, decrypted, and verified using certificates. However, since different application systems use different certification systems and certificate storage methods, it is difficult to implement encrypted signatures between multiple application systems that can be decrypted by another system. The main difficulty of...
