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.
