USB HUB DEVICE FOR PROVIDING DATASECURITY AND METHOD FOR PROVIDING DATASECURITY USING THE SAME

摘要

PURPOSE: A USB hub device for providing data security and a method for providing data security using the same are provided to give a security function to a portable USB storage device by encoding and decoding input/output data through intrinsic chip ID. CONSTITUTION: A USB(Universal Serial Bus) hub controller(101) outputs input data, which are inputted through a data input port, through an output port. A security controller(103) uses an intrinsic semiconductor chip ID as the encoding or decoding key for the data. A CPU(Central Processing Unit) analyzes the input/output data of the USB hub controller, and controls the security controller.
