Systems, apparatuses, and methods to identify bus-off and masquerade attacks against ECUs transmitting on a communication bus from behind a gateway coupled to the communication bus. The disclosure further describes systems, apparatuses, and methods to mitigate against bus-off attacks made against an ECU coupled to a communication bus through a gateway.

Apparatuses and methods can be related to configuring interface protocols for memory. An interface protocol can define the commands received by a memory device utilizing transceivers, receivers, and/or transmitters of an interface of a memory device. An interface protocol used by a memory device can be implemented utilizing a decoder of signals provided via a plurality of transceivers of the memory device. The decoder utilized by a memory device can be selected by setting a mode register of the memory device.

A communication module is configured to communicate a first part of a message packet configured to identify message content contained in the message packet and a second part of the message packet and change the second part of the message packet in response to a trigger. A received message packet's changing portion is compared with the set of the authorized changing portions to determine whether the received message packet is authorized for the common control network. The received message packet is discarded or ignored in response to the received message packet's changing portion not matching at least one of the authorized changing portions in the set of the authorized changing portions.

Systems and methods are presented for secured communications in a controller area network for a vehicle system. A first electronic processor is communicatively coupled to a memory and configured to operate one or more vehicle systems. A second electronic processor is configured to generate message authentication codes to verify data communications between the first electronic processor and at least one other vehicle system controller in the controller area network. The direct memory access (DMA) module is configured to facilitate direct communications between the second electronic processor and the memory so that the first electronic processor can continue to execute other instructions while message authentication codes are generated by the second electronic processor for incoming and outgoing message data.
