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.

Abstract: Disclosed herein are a method for countering an asynchronous attack on a supply chain security protocol and an apparatus for the same. The method includes, in a supply chain security protocol performed by a terminal device into which a dielet is inserted and an authentication server, performing a self-generation mode in which a counter value within the dielet is registered in the authentication server, performing a read-out mode in which whether an asynchronous attack occurs is detected by comparing the counter values respectively stored in the dielet and the authentication server when a message for communication is sent, and replacing a message for the communication with a random value when an asynchronous attack is detected.

Abstract: Disclosed herein is a method for securing an indirect function call according to an embodiment of the present invention. The method may include searching for an instruction that indirectly calls a function in intermediate representation code, calculating the number of functions that have to be allowed to be indirectly called based on the found instruction, identifying the address of a function loaded at the N-th lowest address arbitrarily set in advance, among the functions, the number of which is calculated, identifying indexes for selecting callee functions to be indirectly called based on the found instruction, determining whether to allow the function to be called using the identified indexes, and determining, when the function is allowed to be called, whether to allow the function to be called using the address of a callee function, the memory address of which is N-th lowest, among the callee functions.

Abstract: An apparatus and method for determining the location of a mobile object are disclosed. The apparatus includes a GPS module unit, a mobile communication module unit, a USN module unit, and a control module unit. The GPS module unit receives a GPS signal including the coordinate information of the current location of a mobile object. The mobile communication module unit is operated when the GPS module unit has received the GPS signal, and transmits the coordinate information of the current location of the mobile object and the ID of the mobile object to a location estimation apparatus. The USN module unit is operated when the GPS module unit fails to receive the GPS signal, and broadcasts a beacon signal carrying the ID of the mobile object. The control module unit operates any one of the mobile communication module unit and the USN module unit.
