Claim 10:
11. A system, comprising:
a first network device in a wireless core network, the first network device including a first processor; and
a Network Repository Function (NRF) device, the NRF device including a second processor, wherein the first processor is configured to:
store a NRF certificate for cryptographic exchanges;

wherein the second processor is configured to:
receive, from a NF consumer of the wireless core network, a service request,
bind a digitally signed service request object to an authorization token, wherein the digitally signed service request object is based on a hash value of parameters in the service request,
send, to the NF consumer, a preliminary service response with the authorization token and the digitally signed service request object,

wherein the first processor is further configured to:
receive the service request with the authorization token and the digitally signed service request object,
ensure that the NF consumer is authorized to issue the service request by verifying the service request based on the NRF certificate, the authorization token, and the digitally signed service request object,
generate, after the verifying, a service response that includes a digitally signed service response object, and
