NXP's TJA1152 and TJA1153 are secure CAN transceivers designed to provide a seamless and cost-effective solution for securing classical CAN and CAN FD communication without the need for cryptography. These transceivers belong to a generation of automotive high-speed CAN/CAN FD transceivers that incorporate security functions.
The TJA1152 and TJA1153 act as an interface between a classical CAN or CAN FD protocol controller and the physical two-wire CAN bus. Under normal operating conditions, when no security incidents have been detected, the TJA1152 functions as a standard CAN transceiver with a standby mode, while the TJA1153 offers a sleep mode.
These transceivers are equipped with security features to detect and contain potential security incidents. Some of the security incidents that can be detected include 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, and receiving a CAN message from a remote host with an identifier identical to one uniquely assigned to the local node. By detecting and addressing these security incidents, the TJA1152 and TJA1153 ensure the integrity and reliability of the CAN communication.
In summary, NXP's TJA1152 and TJA1153 secure CAN transceivers provide a robust solution for protecting against security incidents in classical CAN and CAN FD communication. With their built-in security functionalities, these transceivers offer reliable defense mechanisms against flooding, unauthorized message transmission, and tampering, ensuring the secure operation of automotive systems.
