Embodiment 1

[0051] In this embodiment, a system for verifying the validity of a mobile backhaul network certificate is suitable for verifying the validity of a certificate in a domain. The system includes an Online Certificate Status Protocol (OCSP) client, an OCSP responder, and a certificate library;

[0052] The OCSP client is used to send an OCSP query request to the OCSP responder, wherein the request certificate table is carried;

[0053] The OCSP responder is used to request the certificate library to verify the validity of the certificate in the request certificate table after receiving the OCSP query request, and send the received certificate validity retrieval result to the OCSP client;

[0054] The certificate library is used to query the validity of the certificates in the request certificate table according to the request certificate table, and return a certificate search response message to the OCSP responder, which carries the certificate validity search result.

[0055] Th...

Embodiment 2

[0058] In this embodiment, a system for verifying the validity of a mobile backhaul network certificate is suitable for verifying the validity of an inter-domain certificate, including an Online Certificate Status Protocol (OCSP) client, a local OCSP responder, a remote OCSP responder, DNS (domain name Parse server) and remote certificate store;

[0059] The OCSP client is used to send an OCSP query request to the local OCSP responder, which carries the request certificate form and the domain name information of the remote OCSP responder;

[0060] The local OCSP responder is used to query the IP address of the remote OCSP responder according to the domain name information of the remote OCSP responder after receiving the OCSP query request, and send the OCSP query request to the remote OCSP responder, which carries the request certificate table; To send the received certificate validity retrieval result to the OCSP client;

[0061] The remote OCSP responder is used to request ...

Abstract

The invention provides system and method for validity verification of a certificate in a mobile backhaul net. The method comprises the following steps of: when the validity of a domain certificate is verified, the client side of an online certificate status protocol (OCSP) sends an OCSP search request to an OCSP responser, and a request certificate table is carried; after the OCSP responser receives the OCSP search request, a certificate library is requested to verify the validity of the certificate in the request certificate table, and the certificate library searches the validity of the certificate in the request certificate table and transmits the search results of the validity of the certificate to the OCSP client side by the OCSP responser. The invention can efficiently verify the validity of the certificate in the mobile backhaul net in real time.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a system and method for verifying the validity of a mobile backhaul network certificate. Background technique [0002] The security of the mobile backhaul network has received more and more attention. Organizations such as 3GPP, BBF, and NGMN have conducted in-depth analysis on the security requirements of the mobile backhaul network, and certificate management is the basis of the security mechanism of the mobile backhaul network. [0003] 3GPP TS 33.401 proposes to protect the security of the mobile backhaul network based on the NDS (Network Domain Security) mechanism, and the management of NDS certificates is subject to the relevant specifications of TS 33.310. However, TS 33.310 is formulated for network domain certificate management requirements, and is not fully suitable for mobile backhaul network certificate validity verification requirements. Therefore, the certif...
