Abstract
An operation method of a first communication node supporting communications between an Ethernet-based network and a controller area network (CAN) includes: receiving an Ethernet message from a second communication node belonging to the Ethernet-based network; performing an integrity verification on first automotive safety integrity level (ASIL) authentication information included in the Ethernet message; generating a CAN message based on the Ethernet message for which the integrity verification has been completed; and transmitting the CAN message to a third communication node belonging to the CAN.
Claims17
An operation method of a first communication node supporting communications between an Ethernet-based network and a controller area network (CAN), comprising:
- receiving an Ethernet message from a second communication node belonging to the Ethernet-based network;
- performing an integrity verification on first automotive safety integrity level (ASIL) authentication information included in the Ethernet message;
- generating a CAN message based on the Ethernet message for which the integrity verification has been completed;
- and
- transmitting the CAN message to a third communication node belonging to the CAN,
- wherein the CAN message includes second ASIL authentication information, the second ASIL authentication information is used for an integrity verification on the CAN message, and the second ASIL authentication information is generated by the first communication node.
An operating method of a first communication node supporting communications between an Ethernet-based network and a controller area network (CAN), comprising:
- receiving a CAN message from a second communication node belonging to the CAN;
- performing an integrity verification on first automotive safety integrity level (ASIL) authentication information included in the CAN message;
- generating an Ethernet message based on the CAN message for which the integrity verification has been completed;
- and
- transmitting the Ethernet message to a third communication node belonging to the Ethernet-based network,
- wherein the Ethernet message includes second ASIL authentication information, the second ASIL authentication information is used for an integrity verification on the Ethernet message, and the second ASIL authentication information is generated by the first communication node.
A first communication node supporting communications between an Ethernet-based network and a controller area network (CAN), comprising:
- a processor;
- and
- a memory storing at least one instruction executed by the processor,
- wherein the at least one instruction is configured to:
- receive an Ethernet message from a second communication node belonging to the Ethernet-based network;
- perform an integrity verification on first automotive safety integrity level (ASIL) authentication information included in the Ethernet message;
- generate a CAN message based on the Ethernet message for which the integrity verification has been completed;
- and
- transmit the CAN message to a third communication node belonging to the CAN,
- wherein the CAN message includes at least one data unit indicated by a routing table among a plurality of data units included in the Ethernet message, and the routing table indicates data units to be transmitted to the CAN.
