Abstract
A method manages keys in a manipulation-proof manner for a virtual private network. The method includes authenticating a communication terminal on an authentication server by use of a first key over a public network and providing a communication key, which is suitable for the communication over a virtual private network in the public network, for the authenticated communication terminal over the public network. The communication key in the communication terminal is encrypted by a second key, which is provided by a manipulation-protected monitoring device.
