Abstract: Disclosed herein are a one-way data transmission apparatus, a one-way data reception apparatus, and a one-way data transmission/reception method using the apparatuses. The one-way data transmission/reception method uses a one-way data transmission apparatus and a one-way data reception apparatus, and includes receiving data from a high-security zone through a one-way path, generating tag information of the data, sending a message in which the tag information is added to the data to the one-way data reception apparatus, receiving the message from the one-way data transmission apparatus, checking the tag information of the message, and transmitting the data to a low-security zone.

Abstract: Disclosed herein are an apparatus and method for detecting violation of control flow integrity. The apparatus includes memory for storing a program and a processor for executing the program, wherein the processor multiple branch identifier registers to which identifiers of branch targets are written, a set branch identifier instruction configured to command an identifier of a branch target to be written to a branch identifier register at a predetermined sequence number, among the multiple branch identifier registers, and a check branch identifier instruction configured to command a signal indicating detection of a control flow hijacking attack to be issued based on whether a value written to the branch identifier register at the predetermined sequence number is identical to a value of an identifier of a branch target at the predetermined sequence number, wherein the program detects whether a control flow is hijacked based on the multiple branch identifier registers.

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 herein are an apparatus for analyzing non-informative firmware and a method using the apparatus. The method includes detecting a target instruction for firmware analysis in a memory map in non-informative firmware, generating an analysis list based on memory map information corresponding to the target instruction, and generating a visualized analysis result corresponding to the firmware by grouping the entries of the analysis list by preset reference bytes.
