Abstract
A system and method for enabling sensitive authentication information to be under the control of the service provider and transmitting only non-sensitive authentication information to the AC, and for providing a secure technique for generating sensitive authentication information and for securely transmitting to and storing the information in the mobile system (MS) and a storage device controlled by the service provider. The present invention utilizes a secure authentication center (SAC) and a secure A-key management system (SAMS) to perform authentication. The present invention automatically and securely generates and programs an MS and SAMS with the sensitive authentication information while significantly reducing the risk of misappropriation of the sensitive authentication information. The risk of misappropriation is reduced since the sensitive authentication information (or other sensitive information) need not be pre-programmed into the MS, or if it is pre-programmed, the sensitive authentication information can be re-programmed, thereby reducing the potential access to the information by unauthorized people before the MS is sold. In addition, the risk of misappropriation is reduced since the generation and programming system and method is performed automatically using a secured communication technique.
