Abstract: A controller device includes a memory storing instructions. An interface bus is coupled to sensors and configured to operate with a multi-target interface protocol. A processor is coupled to the memory and the interface bus. The processor broadcasts initialization data, according to the multi-target interface protocol, to the sensors. The processor generates, from the initialization data, using at least one cryptographic function, an authentication tag for each sensor. Each authentication tag is specific to a corresponding sensor of the sensors. The processor also unicasts, according to the multi-target interface protocol, each authentication tag to the corresponding sensor of the sensors.

Abstract: A controller device includes a memory storing instructions, an interface bus coupled to peripheral devices and configured to operate with a multi-target interface protocol, and a processor coupled to the memory and the interface bus. The processor broadcasts initialization data, according to the multi-target interface protocol, to the peripheral devices. The processor generates, from the initialization data, using at least one cryptographic function, an authentication tag for each peripheral device. Each authentication tag can be specific to a corresponding peripheral device. The processor creates client objects corresponding to each of the peripheral devices, each client object configured to unicast an authentication tag to the corresponding peripheral device based on a specific address. The processor unicasts, according to the multi-target interface protocol, using the client objects, each authentication tag to the corresponding peripheral device of the peripheral devices.
