Problems solved by technology

When the number of CAs is small, the problem of CA mutual trust can be solved very well, but when a large number of CAs perform cross-certification in pairs, a complex network structure will be formed, which will make the certificate certification path longer or even form a loop, and the certificate policy (CP ) will greatly limit the use of the certificate after multiple mappings

Embodiment Construction

[0135] The specific implementation manner of the present invention will be further described in detail below with reference to the drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0136] Such as figure 1 As shown, the method for realizing CA mutual trust in the embodiment of the present invention is applied to a CA mutual trust system. The CA mutual trust system includes: at least three CA entities, each CA entity forms a point-to-point P2P network and forms a blockchain system; each CA entity stores a blockchain record for recording the operation record of the entity certificate; The method is applied to CA entities. The method includes:

[0137] Step 101, assigning the entity certificate to be issued to the certificate requesting party.

[0138] Step 102: Request consensus on the entity certificate to be issued from other CA entities in the system.

Abstract

The invention provides a method, apparatus and system for implementing CA mutual trust, and an electronic device, and relates to the technical field of communication. The flexibility of implementing the CA mutual trust is improved. The method for implementing the CA mutual trust provided by the invention comprises the following steps: allocating an entity certificate to be signed and issued to a certificate requester; requesting the other CA entities in the system to perform consensus on the entity certificate to be signed and issued; if it is determined that the authentication of the other CAentities on the entity certificate to be signed and issued is passed, signing and issuing the entity certificate to be signed and issued to the certificate requester, wherein the entity certificate to be signed and issued comprises a blockchain authentication mark, and the blockchain authentication mark is an identifier of a blockchain system; and updating a stored blockchain record. By adoptionof the scheme of the embodiment of the invention, the flexibility of implementing the CA mutual trust is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device, system and electronic equipment for realizing CA mutual trust. Background technique [0002] PKI (Public Key Infrastructure) plays a very important role in the field of information security. Whether it is using HTTPS ((Hyper Text Transfer Protocol over Secure SocketLayer, Hypertext Transfer Protocol Security) to access secure websites, or electronic signatures often used in digital commerce / government / office fields, there must be PKI support. [0003] When the PKI relying party verifies the other party's certificate, it needs to build a corresponding certificate authentication path, and there must be a trust starting point in the path, that is, the trust anchor. The trust anchor is usually a self-signed certificate of a CA (Certificate Authority, certificate authority) trusted by the relying party. The number of trust anchors for relying parties...
