Abstract: Disclosed is a system for performing key management of an in-vehicle network. The key management system of the in-vehicle network includes a reception unit configured to receive a shared secret key of a central gateway and a domain gateway, a memory configured to store a program for performing key management of the in-vehicle network using the shared secret key, and a processor configured to execute the program. The processor generates a secret key to be stored in a node of the in-vehicle network using the shared secret key and a unique ID of the node.

Abstract: An electronic device includes a peripheral device, a processor, an interrupt controller configured to manage interrupts generated by the peripheral device and the processor on the basis of a register, and a virtualizer, wherein the virtualizer may be configured to virtualize a portion of the processor and a portion of the at least one peripheral device to generate a first partition, generate first interrupt information corresponding to an interrupt usable in the first partition, generate first processor information corresponding to a portion of the processor usable in the first partition, check whether a configuration of the register is related to at least one of the first interrupt information and the first processor information when the register is configured by the first partition, and allow the configuration of the register when the configuration of the register is related to the at least one information.

Abstract: A transmission method of a domain gateway over a vehicle network based on automotive Ethernet includes receiving, by a domain gateway of a first domain, transmission data on a CAN packet basis from a transmitting-side ECU; transmitting, by the domain gateway of the first domain, the transmission on an Ethernet packet basis to a domain gateway of a second domain; and transmitting, by the domain gateway of the second domain, the transmission data on a CAN packet basis to a receiving-side ECU. The CAN packet includes a CAN ID field, and the CAN ID field includes a CAN message section and an authentication section.
