SYSTEM AND METHOD FOR AUTHENTICATING A NETWORK GATEWAY

摘要

A method of network gateway authenticating involves a network gateway receiving an authentication request from a communications terminal. The communications terminal is in communication with an identity token. The authentication request includes a token cryptogram generated from a cryptographic key stored on the identity token. The network gateway transmits the authentication request to a communications network, and receives an authentication response from the communications network in accordance with a validity of the token cryptogram. The authentication response includes a gateway authentication certificate. The gateway authentication certificate is configured to authenticate the network gateway to a network device of the communications network.
