Abstract: A risk-aware access control system and related methods are provided. In accordance with one aspect of the present disclosure, there is a provided a method of risk-aware access control, comprising: detecting a request to perform an action with respect to two factors, the factors being of a factor type selecting people, devices, documents, and location, wherein the factors are of a different factor type; determining a coupling associated with the requested action based on the factors of the requested action; determining a risk level associated with the coupling; denying the requested action in response to a determination that the risk level does not match a security policy; and allowing the requested action in response to a determination that the risk level matches the security policy.

Abstract: A vehicle device for monitoring data traffic with components of a motor vehicle in a motor vehicle includes one or more interfaces to communicate with at least one transceiver of a first radio system and at least one transceiver of a second radio system. The device includes a monitoring module to receive information about a data transmission via the one or more interfaces and the first radio system and to transmit data via the one or more transceivers and via the second radio system. The network device for a network component for monitoring a data transmission to at least one component of a motor vehicle includes at least one interface to communicate with at least one other network component and a monitoring module to receive information about a request for a data transmission and to transmit information about the request via a radio system to the motor vehicle.

Abstract: The configuration of a wireless communication link between a mobile device and a vehicle including authentication of the mobile device, automatic adjustment of a configuration of the mobile device for the wireless communication link on the basis of the authentication, and automatic adjustment of a configuration of the vehicle.

Abstract: A method for simulating a communication system, and simulation system for a communication system and computer program, the communication system having a communication protocol which regulates a communication between at least two transmitter-receivers of the communication system via a common communication channel in such a way that a first transmitter-receiver transmits a data packet only when no use of the communication channel by a second transmitter-receiver is indicated to the first transmitter-receiver, includes sending a data packet by at least the first transmitter-receiver via the common communication channel even when at least the second transmitter-receiver is using the communication channel.

Abstract: A method and an apparatus for estimating an expected reception quality in an interval of time for car-to-X communication including a receiving device for acquiring data packets and a memory, wherein the memory stores at least one empirically determined variable for reception patterns of data packets in a first interval of time, which variable indicates or can be used to determine how high the probability is of a data packet or n data packets being successfully received in a subsequent, second interval of time, wherein the apparatus is designed so that the reception pattern is determined for a first interval of time before the interval of time and the associated probability for the interval of time is read from the memory, wherein a warning message is generated and/or a transmission parameter and/or a functionality of a driver assistance function is/are changed on the basis of the probability.

Abstract: A method for estimating the probability that a data packet wirelessly transmitted from a transmitter, which is a traffic infrastructure object or a vehicle, to a receiver will be received. The method includes estimating a signal quality of the data packet and estimating the probability that the data packet will be received on the basis of the estimated signal quality.
