Summary:给出了为在其家庭系统外旅行的订户提供本地认证的方法和装置。订户标识令牌(230)通过根据从移动单元(220)秘密保留的密钥产生签名(370)而提供认证支持。移动单元(220)被编程在订户已移去他或她的令牌之后错误地保留来自订户标识令牌(230)的密钥，它被阻止随后访问该订户的账户。 Methods and apparatus are presented for providing local authentication of subscribers travelling outside their home systems. A subscriber identification token 230 provides authentication support by generating a signature 370 based upon a key that is held secret from a mobile unit 220. A mobile unit 220 that is programmed to wrongfully retain keys from a subscriber identification token 230 after a subscriber has removed his or her token is prevented from subsequently accessing the subscriber's account.
