发明名称 Fast update message authentication with key derivation in mobile IP systems
摘要 The present invention performs a Binding Update or a Location Update message authentication independently and terminal-specifically in a home SAE gateway. A key, which is derived in a home AAA server from an initially set long term key, is given to a visited network for encrypting the update messages in Proxy Mobile IP. In Client Mobile IP, the key is transmitted to a mobile node for update message encryption. When the update message is received in the home SAE gateway, the key can be derived independently in the home SAE gateway without any key requests between the gateway and the home AAA server. Thus, it is possible to authenticate the binding or location update messages by verifying the two signatures. The present invention can also be implemented on a lower hierarchy of the system. The invention can be implemented in 3GPP standard releases enhanced with LTE technology, for instance.
