Abstract
An access specific key is provided for securing of a data transfer between a mobile terminal and a node of an access net. For authentication of the mobile terminal, a authentication server generates a session key, from which a basic key is derived and transferred to an interworking-proxy-server. The interworking-proxy-server derives the access specific key from the transferred basis key and provides the key to the node of the access net.
