Abstract
Data transmitted in a system having at least three instances is authenticated between two of these instances. Some of the instances implement an authentication mechanism so that a first instance can authenticate itself to a neighboring instance trusting the first instance. The data to be transmitted by the first instance as a source instance to a non-neighboring target instance is authenticated by the source instance and passed to an intermediate instance that trusts the source instance. The intermediate instance checks the authentication and provides the data with the identity label of the source instance, reauthenticates the data, and passes it to a neighboring instance trusting the intermediate instance. The neighboring instance checks the authentication, reauthenticates the data provided with the identity label of the source instance and passes it to a neighboring instance that trusts it, this process being repeated until the data to be transmitted reaches the target instance.
