What changed

This patent application describes a service access control system where a service authorization server receives service authorization requests from terminal devices for target applications. The server determines whether to allow access based on locally configured access regulation and control policies. Upon successful authorization verification, the server issues a service authorization certificate with a specified time limit to the terminal device, which then sends a service access request to a routing node. After credibility verification passes, the request is forwarded to the target application's server.

Technology companies and software developers implementing authentication and access control systems should note this patent's broad claims covering certificate-based service authorization with time limits. While this is a patent application rather than an issued patent, companies developing similar authentication mechanisms may want to conduct freedom-to-operate analyses. The CPC classifications (H04L 63/0823, H04L 63/108) indicate focus on cryptographic key/credential management and network access control security measures.

Abstract

Provided in the present application are a service access method, a terminal device, a server, and a routing node. The solution comprises: a service authorization server receiving a service authorization request, which is sent by a terminal device, for a target application; on the basis of an access regulation and control policy, which is locally configured for the target application, the service authorization server determining whether to allow the terminal device to perform service access on the target application; after service authorization verification is passed, the service authorization server configuring, for the terminal device, a service authorization certificate and a time limit of the service authorization certificate, such that the terminal device sends, to a routing node, a service access request for the target application; and after the service authorization credibility verification is passed, forwarding the service access request to an application server of the target application.
