摘要： 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, 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, and for enabling a mobile station to utilize features supported by the visited system even if the MS home system does not support the feature. The present invention utilizes a secure authentication center (SAC) and a secure A-key management system (SAMS) to perform authentication. The SAC can be positioned locally in a home system, or it can be centrally located, for example, between systems. The SAC can be connected to many SAMS. Each SAMS stores sensitive authentication information for a group of MS's. During authentication, the SAC generates a request signal to the appropriate SAMS which generates a unique signal based upon the secret authentication data and other data stored therein. However, the sensitive authentication data is not sent to the SAC. The SAC performs authentication using the unique signal transmitted by the SAMS.

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.
摘要翻译：一种用于使得敏感认证信息处于服务提供商的控制下并且仅将非敏感认证信息发送到AC的系统和方法，并且用于提供用于产生敏感认证信息的安全技术以及用于安全地传送和存储信息在移动系统（MS）和由服务提供商控制的存储设备中。本发明利用安全认证中心（SAC）和安全A密钥管理系统（SAMS）进行认证。本发明通过敏感认证信息自动安全地生成和编程MS和SAMS，同时显着降低了盗用敏感认证信息的风险。由于敏感认证信息（或其他敏感信息）不需要预编程到MS中，或者如果它被预先编程，敏感的认证信息可以重新编程，从而减少潜在的访问，从而降低了盗用风险未经许可的人在MS出售之前的信息。此外，由于使用安全通信技术自动执行生成和编程系统和方法，所以盗用风险降低。
