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 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: An electric vehicle and a device and method for charging the electric vehicle are disclosed. The device for charging an electric vehicle includes a charger cable communication unit, a charger security unit, and a control unit. The charger cable communication unit receives encrypted electric vehicle charging information from an electric vehicle. The charger security unit decrypts the encrypted electric vehicle charging information. The control unit determines whether the decrypted electric vehicle charging information is identical with charger charging information. The charger security unit encrypts the charger charging information if the control unit of the device for charging an electric vehicle determines that the decrypted electric vehicle charging information is not identical with the charger charging information. The charger cable communication unit sends the encrypted charger charging information to the electric vehicle. The control unit charges the electric vehicle when an acknowledgement message is received from the electric vehicle.
