Abstract:
1. A non-transitory computer-readable storage medium, comprising computer instructions that, when executed by a processor, causes the processor to perform operations comprising: generating an authentication center private key at an authentication center, wherein the authentication center comprises a network proxy including a communication interface for communicating with a gateway that provides voice, video, internet protocol television and data communication services between voice over internet protocol terminals; computing an authentication center public key based at least in part on the authentication center private key and a reference point in a cryptography algorithm; receiving a communication device public key computed by a communication device based at least in part on a communication device private key and the reference point in the cryptography algorithm, wherein the communication device private key is stored in an identity module of the communication device, wherein the communication device private key is provided to the communication device from a third party network, wherein the cryptography algorithm is an elliptic curve algorithm having a base point, wherein the third party network is operated by a single party source, and wherein the authentication center private key, the communication device private key, and the elliptic curve algorithm and base point are supplied to the authentication center and the communication device by the single party source; supplying the authentication center public key to the communication device; computing a shared secret key based at least in part on the authentication center public key and the communication device public key; and authenticating the communication device based at least in part on the shared secret key, wherein the shared secret key is temporarily stored by an authentication server, wherein the authentication center private key is provided to the authentication server from the third party network.
