Abstract (en)

[origin: WO2006082181A1] The invention relates to a method for locking on or legal interception of encrypted communication connections, preferably in a peer-to-peer network. If all users in a communication network have a digital certificate, a good authentication and an end-to-end encryption of communication data is possible. A modification of network elements is disclosed to nevertheless provide legal tapping from authorized positions. The above can be used on a special tapping mode, in which the keys for all incoming and outgoing messages are provided to an authorized control position.
