NXP's new secure CAN transceiver TJA1153A provides a seamless and very cost-effective solution for securing classical CAN and CAN FD communication without cryptography. The TJA1153A belongs to a new generation of automotive high-speed CAN/CAN FD transceivers, offering security functions. It provides an interface between a classical CAN or CAN FD protocol controller and the physical two-wire CAN bus. As long as no security incidents have been detected, the TJA1153A behaves like a standard CAN transceiver with Sleep mode. The security incidents that can be detected and contained are: * Flooding the bus from the local node * Transmitting a CAN message with an identifier that has not been assigned to the local node for transmission * Receiving a CAN message from a remote host with an identifier that is identical to one uniquely assigned to this local node * Tampered messages
