Abstract:
Several use cases demand for the setup of a separate, dedicated communication channel that provides a specific quality of service, or to separate communications of different criticality. Different properties of communication channels are performance, latency, but may be also security related. In several cases, a reliable association to an already established communication channel is required. Specifically, if a first communication channel has been securely established, a cryptographic binding of a second communication channel to this first communication channel is needed. One example use case is the charging of electric vehicles. Besides the charging control, also value-added services like software updates for the infotainment system shall be provided. To avoid interfering with the charging-related control communications, a second, separate communication channel is established. The two communication channels require different quality of service. However, authorization to access value-added services and maybe also the billing of consumed value-added services shall be to bound to the user that has been authenticated in the setup of the first communication channel. The paper proposes a general solution that allows establishing arbitrary communication channels of different nature on the example of an electric vehicle and a charging station, all bound to the actual charging control session.
