Abstract: Disclosed are an apparatus and method for communicating data in an in-vehicle network. The method, performed by apparatuses for communicating data on a transmission side and a reception side, includes determining, by the apparatus on the transmission side, whether data collected from the in-vehicle network is changed; creating, by the apparatus on the transmission side, an authentication value based on the determination as to whether the data is changed, creating a message including the data and the authentication value and transmitting the message to the apparatus on the reception side; receiving, by the apparatus on the reception side, the message; creating, by the apparatus on the reception side, a verification value using data extracted from the message; and verifying, by the apparatus on the reception side, the integrity of the apparatus on the transmission side by comparing the authentication value extracted from the message with the verification value.

Abstract: Disclosed herein are a method and apparatus for randomizing the address space layout of an embedded system based on hardware. The method is configured such that the hardware loader of the embedded system randomly arranges the respective address regions of multiple peripheral devices and memory using a random number each time a program is loaded, such that the respective random start addresses of the multiple peripheral devices and the memory, which are set based on the randomly arranged address regions, are recorded in an address table, and such that program code loaded into the memory is reengineered based on the address table so as to match the randomly arranged address regions.

Abstract: Disclosed herein are a lightweight intrusion detection method and apparatus for a vehicle network. The lightweight intrusion detection method may include collecting Ethernet packets from a domain gateway of a vehicle that provides a mirroring port, performing a primary intrusion detection check on the Ethernet packets using a rule-based intrusion detection technique, and performing a secondary intrusion detection check on the Ethernet packets using a machine learning-based intrusion detection technique when no intrusion attack is detected as a result of the primary intrusion detection check.
