System and method for enabling secure service-based communications via 5G proxies

This invention describes a system for secure communication between different components within a 5G wireless network. When one network function requests a service from another, the request is routed through a central proxy. A network repository function helps discover the service and ensures the request is digitally signed and tied to an authorization token, which the service provider then verifies before responding with its own signed message. The claims specifically detail the network repository function's role in binding the signed request to an authorization token.
