Abstract: A method and replay unit for sending secured messages via a messaging system to a receiver ECU to be tested, wherein the replay unit is connected to the device under test via the messaging system, wherein the replay unit is set up to receive first secured messages to be replayed, to remove from the first secured messages a first counter value and a first authenticator, and to generate a second authenticator by means of a second counter value, an encryption algorithm and a key, and wherein the replay unit is set up to generate second secured messages by adding the second counter value and the second authenticator to the first messages, and wherein the replay unit is further adapted to send the second secured messages to the recipient device under test via the messaging system.

Abstract: A computer-implemented method for simulating a restbus control unit network that includes at least two restbus control units connected through a bus system. The restbus control unit network is connected to at least one additional control unit through the bus system. The communication relationships of the restbus control units are described, program code for simulating the restbus control units is generated based on the communication relationships. The restbus control unit network is simulated on a simulation computer via an executable version of the program code. Simplified and flexible simulation of the restbus control unit network is made possible in that a single, joint restbus control unit model is generated for the restbus control units as program code for simulating the restbus control units.

Abstract: A method in which the propagation times of a target network are simulated in an actual network, wherein the topology of the target network includes a number of senders and a number of receivers, and wherein the topology of the actual network includes one or more of the senders and receivers. A path between a first sender and a first receiver in the topology of the actual network differs from the path between the first sender and the first receiver in the topology of the target network, wherein in the actual network at least one first message of the first sender is received through a first network interface by a gateway having at least two network interfaces, is delayed by a delay, and is sent through a second network interface on a path to the first receiver.
