Abstract: Disclosed herein are a garbage collection method and apparatus. The garbage collection method includes when an area dynamically allocated through a malloc( ) function or a new operator of a standard C library is deallocated through a free( ) function or a delete operator, inserting the deallocated area into a quarantine list, recording a base address and an end address of each of areas inserted into the quarantine list in a CSR_quarantined_chunks register, finding a physical address of a memory page used by a processor and searching data in the memory page for a value included in a quarantined area of the CSR_quarantined_chunks register, when a value included in the quarantined area is not present, setting a state flag bit of the register to 0, and deleting an area which the state flag bit is 0 from the quarantine list, and inserting the area into a free list.

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 managing an access control list based on an automotive Ethernet and an apparatus for the same. The method includes analyzing a new access control rule that is input to a vehicle in which the automotive Ethernet is applied, searching for any one target unit to manage the new access control rule in consideration of at least one of a destination and an application target corresponding to the new access control rule, and storing the new access control rule by transmitting a storage request message corresponding to the new access control rule to the target unit.

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 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.
