Abstract
RFID(Radio Frequency Identification) system is an automated identification system that consists of tags and readers. They communicate with each other by RF signal. As a reader can identify many tags in contactless manner using RF signal, RFID system is expected to do a new technology to substitute a bar-code system. But RFID system creates new threats to the security and privacy of individuals, Because tags and readers communicate with each other in insecure channel using RF signal. So many people are trying to study various manners to solve privacy problems against attacks, but it is difficult to apply to RFID system based on low-cost Gen2. Therefore, We will propose a new encryption scheme using matrix based on Gen2 in RFID system in paper, and We will analyze our encryption scheme in view of the security and efficiency through a simulation and investigate application environments to use our encryption scheme.
