Estimating the term…
A system and method for authentication of a communication device is disclosed. A system that incorporates teachings of the present disclosure may include, for example, a communication device having a controller element to compute a shared secret key based at least in part on a communication device (CD) private key and a cryptography algorithm, wherein the CD private key is stored in an identity module of the communication device and is unknown to an authentication center, and wherein the communication device is authenticated by the authentication center based at least in part on the shared secret key. Additional embodiments are disclosed.
A computer-readable storage medium, comprising computer instructions for:
A communication device, comprising a controller element to compute a shared secret key based at least in part on a communication device (CD) private key and a cryptography algorithm, wherein the CD private key is stored in an identity module of the communication device and is unknown to an authentication center, and wherein the communication device is authenticated by the authentication center based at least in part on the shared secret key.
An identity module of a communication device, the identity module comprising a memory updated with a communication device (CD) private key unknown to an authentication center, wherein the communication device computes a shared secret key based at least in part on the CD private key, an authentication center (AC) public key received from the authentication center, and a cryptography algorithm.
A method of authenticating a communication device, comprising:
