Communication device and method for performing encrypted communication in multipoint networks

摘要

A communication device for performing encrypted communication with at least one further communication device in a communication network is provided. Advantageously, the device is adapted to communicate with a plurality of further communication devices. The communication device comprises a communication unit and a cryptographic unit. Moreover it comprises a key encryption key generator configured to generate at least one key encryption key jointly with the at least further communication device, using the communication unit. Also, it comprises a traffic encryption key generator configured to generate a traffic encryption key, specific to the communication device, for encrypting traffic data by the communication device. The cryptographic unit is preferably configured to encrypt the traffic encryption key using the at least one key encryption key. Moreover, the communication unit is preferably configured to transmit the encrypted traffic encryption key to the at least one further communication device.
