The proposed system can achieve more safety of RFID system with the 2-step authentication procedures for the enhancement about the security of general RFID systems. After it has authenticated RFID tag, additionally, the proposed system extract the characteristic information in the user image for acquisition of the additional authentication information of the user with the camera. In this paper, the system which was proposed more enforce the security of the automatic entrance and exit authentication system with the cognitive characters of RFID tag and the extracted characteristic information of the user image through the camera. The RFID system which use the active tag and reader with 2.4GHz bandwidth can recognize the tag of RFID in the various output manner. Additionally, when the RFID system have errors. the characteristic information of the user image is designed to replace the RFID system as it compare with the similarity of the color, outline and input image information which was recorded to the database previously. In the experimental result, the system can acquire more exact results as compared with the single authentication system when it using RFID tag and the information of color characteristics.

기존의 RFID 인증 프로토콜은 트래킹 공격이나 스푸핑 공격에 취약하다는 단점을 가지고 있다. 특히 해쉬기반이나 랜덤 해쉬기반 RFID 인증 프로토콜은 스푸핑 공격으로 인하여 태그와 리더간의 인증이 안전하지 못한 프로토콜이며 해쉬체인 RFID 인증 프로토콜은 리더인증이 곤란한 일방향 인증 프로토콜이다. 본 논문에서 제안하는 프로토콜은 해쉬함수와 RNG(난수생성기)만을 사용하기 때문에 저가의 수동형 RFID 시스템에서 구현이 가능할 뿐만 아니라, 트래킹 공격과 스푸핑 공격에 안전하고, 태그와 리더간의 양방향 인증이 가능한 RFID 인증 프로토콜이다.

In this paper, we proposed a new secure RFID(Radio Frequency IDentification) mutual authentication protocol on insecure communication channel which assumed that all communication channels between the database, the reader and the tag are insecure communication channels. The proposed protocol used a secure one-way hash function and the goal is to improve search time of a tag ID and overload of hash calculational load in DB. In addition, the proposed protocol supports not only basic security requirements to be provided by RFID mutual authentication protocol but also forward secrecy, and the tag does not generate a random number to reduce overload of processing capacity in it.

Recently, RFID system is a main technology to realize ubiquitous computing environments. Because RFID system that is an automatic identification technology using radio frequency is a system to read and write the data of the entity. Therefore, many companies are interested in RFID system to reduce supply chain management and inventory control cost. However, for providing secure service, RFID authentication technology secure against tracking by an adversary is researched first. In this paper, we proposed security level based RFID authentication protocol providing reduce computational and communicational workload in the back-end database. The proposed protocol is secure against reply attack, spoofing attack, traffic analysis, and location privacy, since the proposed protocol based on the security of the hash function.

RFID is applied in various industry area. The purpose of RFID system is authentication of objects. After Tag's certification, RFID system start to process to be wanted. A RFID electric motor recognizes Tag's action and tails. The application of this system is very wide. For example, a cart in shopping Mall follows customer with a proper Tag. Customer may be very convenient if the cart follows customer autonomously as recognizing the direction of Tag. In this parer, we studied about RFID system that follow objects with a Tag. Finally, we experimented and analysed the proposed system, with Tag, Reader, host computer and electric motion motors.

This paper proposes an authentication protocol based on hash and AES safe from various types of attacks in order to assure the security of communication between tags and readers, which exchange data with each other wirelessly in a RFID system. The proposed authentication protocol resolves a problem in existing hash-based protocols whereby the same hidden value is generated for the same identification in each session. In order to hide tag identification information a number of complicated calculations were required, but using the proposed AES protocol reduces such calculations, strengthens security against replay attack, spoofing attack, traffic analysis, eavesdropping, etc. and assure mutual authentication between tags and readers.

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. So, this paper proposes a new authentication protocol which provides not only unlimited access to Tag&Reader and connection between Tag and Reader bet also provides authentication mechanism by defining the key distribution.

Nowadays, low-cost radio frequency identification (RFID) technique, is recognizable without the physical contact between the reader and the tag, has been attracting more and more interests from both industry and academic institutes. however, it causes the serious privacy infringement such as excessive information exposure and user's location information tracking due to the wireless characteristics. The security problem of read only tag can be only solved by physical method. In this paper, we propose a low-cost authentication protocol which can be adopted for read-only RFID tag using XOR and Partial ID. The proposed protocol is secure against reply attacking, eavesdropping and spoofing attacking so that avoiding the location privacy exposure

RFID system is the contact-less recognition technology and use for distribution system, environment, transport, security and so on. However, it may create many security relevant problems such as privacy because constraints of RFID communication environment. So several methods of resolving these problems have been proposed. Recently, Shin and Park proposed an efficient RFID authentication protocol with protecting user's privacy using hash function and exclusive-OR.. But Ahn and Bu et al. poia problem that a attacker can to masquerade as malicious reader because their protocol can't providing mutual authentication.nted out weakness of Shin and Park's protocol and proposed more secure and efficient protocol. Unfortunately, Ahn and But's protocol has In this paper, We propose an improved RFID authentication protocol providing mutual authentication. The proposed protocol has advantages that providing mutual authentication between a tag and a reader, secure against replay attack and spoofing attack. Also, it guarantees anonymity of RFID tag and secure against location tracking attack by collusion of malicious readers.

Recently arithmetic circuit of lightweight AES symmetric key algorithm that can apply to passive tag have been developed, then security protocol of RFID system using AES symmetric encryption techniques have been proposed. This paper proposed security enhancement protocol of RFID system using lightweight AES arithmetic circuit and random number generator of passive tag. The proposed protocol have AES algorithm and random number generator at server, reader, tag, and transmit encrypted message by separate secret key using random number at each session. The mutual authentication of tag and reader used reader random number and tag random number. As a result, proposal protocol reduce authentication steps of the existing mutual authentication protocol, and reduce amount of computation of tag, and demonstrate as secure protocol to every attack type of attacker by decrease communication step of Air Zone.
