토큰키와 해쉬함수를 이용한 RFID 인증 프로토콜 설계

Abstract

RFID is method used on wireless system. However, this mechanism is not used for authentication and security. Therefore, it is very vulnerable to attacks such as dropping attacks and traffic attacks. the RFID Tags are of the limited nature due to environment factors and there is greater constraints in designing authentication protocol. If we do not RFID to secure corporate information and product all the information will be exposed. The attacker will break into the RFID system and stop the distribution system. A few companies used Hash in order to prevent attacks. However, this method has a problem. Hash is based on ID of a tag that it used authentication. But there is a problem that ID was flowed out from this method. As a database is maintained based on Tag's ID. As Tag's ID is exposed attackers can easily get information of tag. So they can easily So, this paper proposes a new authentication protocol which provides authentication mechanism by defining the key distribution. And a new authentication protocol mechanism using Hash function.
