    摘要： In one embodiment, a traffic encryption key is generated based on a count value associated with a mobile. The count value is indicative of network accesses by a mobile, and the traffic encryption key is for encrypting communication traffic between the mobile and a base station. Generation of the traffic encryption key at a base station may be triggered by receipt of a message indicating that the mobile may handoff to the base station. In this embodiment, the message includes the count value. In another embodiment, the traffic encryption key is generated based on the count value and a key count. The mobile may trigger updating the traffic encryption key by changing the key count, and sending the new key count to the base station in a traffic encryption key update request message.

    摘要： The present invention provides a method involving a femtocell in communication with an Internet Protocol Multimedia Subsystem (IMS) network. In one embodiment, the femtocell operates according to code division multiple access (CDMA) standards. The method includes receiving, from the femtocell and at a first secure entity in the IMS network, first authentication information generated by the mobile unit using a first random number broadcast by the femtocell in a global challenge. The method also includes receiving, from a second secure entity in the secure network, at least one security key formed based on the global challenge and second authentication information for uniquely challenging the mobile unit. In one embodiment, the second secure entity is a CDMA-based authentication server. The method further includes providing the security key(s) to the femtocell in response to authenticating the mobile unit based upon the second authentication information.

    摘要： A method and apparatus for performing authentication in a communications system is provided. The method includes receiving a request for authentication from a server, the request for authentication including a first and a second random challenge, and comparing the first random challenge and the second random challenge. The method further includes denying the request for authentication in response to determining that the first random challenge is substantially the same as the second random challenge, and transmitting an encoded value to the server in response to determining that the first random challenge is different from the second random challenge, wherein the encoded value is generated based on the first and second random challenge and a key that is not shared with the server.
