Method for safeguarding data traffic between a first terminal and a first network and a second terminal and a second network
Abstract:
To safeguard data transmission, a first terminal communicates in a first network with the aid of at least one session key and a second terminal communicates in a second network with the aid of at least one session key. The first terminal is connected to the second terminal through a local interface. In the first terminal, at least one first session key is determined and at least one second session key is derived from the first session keys. At least one second session key is transmitted to the second terminal through the local interface by a safety protocol. The second terminal is authenticated to the second network by at least one second session key or by the key derived from the second session key(s) through an authentication protocol.
