Abstract
Security for a USB device is conducted in a protection mode for USB data by hooking an import table of a USB bus class driver, identifying a target IRP, into which the USB data to be protected is inputted, during the hooking routine, and intercepting a real USB data from the IRP. Therefore, input/output data of every USB devices, including a USB keyboard, can be protected in a USB bus class driver level to which a USB input/output request packet is transferred for the first time, thereby protecting the input/output data of the USB devices more safely and basically.
