The RFID system is very useful in various fields such as the distribution industry and the management of the material, etc. However, the RFID system suffers from various attacks since it does not have a complete authentication protocol. Therefore, this paper propose the authentication protocol that used key server to resist various attacks including DoS(Denial of Service) attack. For easy implementation, the proposed protocol also uses CRC, RN16 generation function existing in EPCglobal class 1 gen2 protocol. This paper performed security analysis to prove that the proposed protocol is resistant to various attacks. The analytical results showed that the proposed protocol offered a secure RFID system.

RFID(Radio Frequency IDentification) system is an automated identification system that basically consists of tags and readers and Back-End-Databases. Tags and Readers 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 replace a bar-code system in supply-chain management and payment system and access control and medical record and so on. However, RFID system creates new threats to the security of systems 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 these problems against attacks, But they are difficult to apply to RFID system based on EPCglobal UHF Class-1 Generation-2 tags. Recently, Chien and Chen proposed a mutual Authentication protocol for RFID conforming to EPCglobal UHF Class-1 Generation-2 tags. we discover vulnerabilities of security and inefficiency about their protocol. Therefore, We analyze vulnerabilities of their protocol and propose an efficient mutual authentication protocol that improves security and efficiency.

This paper is intended to trace and management of drug based on RFID Technology at a circulation market, from manufacturer to end user, of drug. To avoid counterfeit and generic drug and establish of order in the circulation of drug, at the moment of manufacturing, tags for each bottle and each box are tagged. and then from factory to hospital, through whole logistics, e-pedigree for the drug is made and monitored. Using inventory information, it is easy to manage and control stock of drug. In addition to, RFID System enables storing and delivery to be simple, process time to be shortened. As this research is to study of applying RFID to drug, in this paper, standard RFID code for drug is suggested and tried to apply domestic middle win. Finally, the result of tag pattern design and how to tag for the drug based on 90Mhz is proposed
