Abstract: Disclosed herein are an in-vehicle network apparatus and method. The in-vehicle network apparatus includes one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program is configured to verify the integrity of software stored in advance in the executable memory, to generate a key table by sharing authentication information with a communication target, and to exchange an encrypted message with the communication target using the key table.

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: Disclosed herein are a method for replacing vehicle parts using an in-vehicle network based on an automotive Ethernet and a system for the same. The method is configured such that a vehicle diagnosis module included in a vehicle performs vehicle self-diagnosis, such that the vehicle and a vehicle manufacturer server perform an authentication process for a new part when a vehicle part is replaced based on a vehicle part replacement agreement procedure between the terminal of a vehicle owner and the maintenance terminal of a vehicle maintenance company, and such that the terminal of the vehicle owner checks whether replacement of the vehicle part is performed normally by requesting an integrity check result from each of the vehicle and the vehicle manufacturer server when the maintenance terminal transmits a part replacement completion message to the terminal of the vehicle owner after completion of the authentication process.

Abstract: The present invention relates to a memory virtualization-based snapshot boot apparatus and method. The memory virtualization-based snapshot boot apparatus includes hardware unit including a processor, memory, and storage, the storage storing status information corresponding to an operating system, and a Virtual Machine Monitor (VMM) operated by the processor and configured to operate the operating system by loading the status information into the memory. In accordance with the present invention, technology for loading only a part of a snapshot image and booting a system is implemented using virtualization technology, thus shortening the booting time of the system.
