    • We disclose various embodiments that enable a mobile terminal to authenticate a base station before the mobile terminal proceeds to attach to the corresponding network and/or camp on the corresponding cell, e.g., during the initial network selection and attachment or during an idle mode. In an example embodiment, the authentication processing includes the mobile terminal generating and sending to a candidate base station a system query with a nonce. The candidate base station is deemed to be authentic only if the acknowledgement generated and transmitted in response to the system query includes a copy of the nonce properly signed by a digital signature generated using one or more security keys. In some embodiments, the system query may also include a request for GPS coordinates and/or selected system information signed using a digital signature, which the mobile terminal may beneficially use to further strengthen the protection against a spoofing attack.
    • 我们公开了各种实施例,这些实施例使得移动终端能够在移动终端继续附着到对应的网络和/或驻留在对应的小区之前(例如,在初始网络选择期间和 附件或在空闲模式期间。 在示例实施例中,认证处理包括移动终端生成并向候选基站发送具有随机数的系统查询。 只有响应于系统查询产生并发送的确认包括由使用一个或多个安全密钥产生的数字签名正确签名的随机数的副本时,候选基站才被认为是可信的。 在一些实施例中,系统查询还可以包括对使用数字签名签名的GPS坐标和/或选定的系统信息的请求,移动终端可以有利地使用该数字签名来进一步加强对抗欺骗攻击的保护。
