The concept of Smart-Homes is becoming more and more popular. It is anticipated that Radio Frequency IDentification (RFID) technology will play a major role in such environments. We can find many previously proposed schemes that focus solely on: authentication between the RFID tags and readers, and user privacy protection from malicious readers. There has also been much talk of a very popular RFID application: a refrigerator/bookshelf that can scan and list out the details of its items on its display screen. Realizing such an application is not as straight forward as it seems to be, especially in securely deploying such RFID-based applications in a smart home environment. Therefore this paper describes some of the RFID-based applications that are applicable to smart home environments. We then identify their related privacy and security threats and security requirements and also propose a secure approach, where RFID-tagged consumer items, RFID-reader enabled appliances (e.g., refrigerators), and RFID-based applications would securely interact among one another. At the moment our approach is just a conceptual idea, but it sheds light on very important security issues related to RFID-based applications that are beneficial for consumers.

The information flow through RFID techniques such as, standardized EPC and EPCglobal network suggests new change in the method of cooperating and sharing information in the supply chain. Common function should be prepared for communication, security techniques, and business processes based on the EPCglobal standard to introduce efficient RFID techniques. And the standard architecture which can deal with the RFID environment flexibly is quite necessary. Therefore, this paper suggests Enterprise Application Framework (EAF) for developing efficient and secure RFID applications. EAF offers essential services to develop RFID enterprise systems : a communication environment which uses various standard communication protocols, a security function based on PKI, and abstract business services for flexible introduction of RFID businesses. It simplifies the RFID business integration, minimizes the development complexity, and thus EAF is expected to reduce the cost of RFID application development. EAF guarantees constructing secure RFID applications due to PKI-based security mechanism.

Since most of recently launched smart devices support NFC(Near Field Communication), RFID applications are tend to be replaced. For instance, previous RFID application areas such as entrance control, mobile e-ticket, electronic payment and et. al are subject to change using NFC. Due to the limitation of passive communication in RFID, it is impossible to cover all security requirements of authentication and authorization mechanism that wide areas of applications demand. Therefore authentication and authorization mechanism based on NFC is very attractive to such applications because active communication methods make it possible to be highly secure in authentication and authorization. In this paper, authors propose a new approach of secure authentication and authorization mechanism using NFC smart devices based on EAP(Extensible Authentication Protocol) and AAA(Authentication, Authorization and Accounting) protocols.

In many applications a reader needs to determine whether a particular tag exists within a group of tags without a server. This is referred to as serverless RFID tag searching. A few protocols for the serverless RFID searching are proposed but they are the single tag search protocol which can search a tag at one time. In this paper, we propose a multi-tag search protocol based on a hash function and a random number generator which can search some tags at one time. For this study, we introduce a protocol which can resolve the problem of synchronization of seeds when communication error occurs in the S3PR protocol[1], and propose a multi-tag search protocol which can reduce the communication overhead. The proposed protocol is secure against tracking attack, impersonation attack, replay attack and denial-of-service attack. This study will be the basis of research for multi-tag serach protocol.

At present, RFID system is highly welcomed as a substitute system with its bar code recognition system and self recognition equipment. Consequently, the system has multi applications and can be complementing to its security. In particular, RFID system is significantly related with electronic transaction equipments : transportation card, ID card in check point, attendance sheet. Based upon these characteristic, the system is becoming extremely popular in the field of logistics, harbor and stock management, animal control and product circulation & distribution. In this dissertation, I would like to present a more efficient and stable remote entry control system with the network-based TCP/IP. It is a simple example of ubiquitous computing function. Above all, approved protocol system should be applied to the remote entry control function. Its efficient function with the applied approval protocol based-remote entry control system should be confirmed. Therefore, a preliminary test should be prerequisite in automatic entrance function with the embedded and TCP/IP-based RFID system.

As port competitiveness is becoming more important in the global market environment RFID (Radio Frequency Identification) Is also becoming a crucial enabler In implement efficient visible, secure and productive ports. However there Is a lack of practical validated RFID technology acceptance cases in the port logistics industry until now, even though various related projects have been undertaken. In this study, we applied 13.56MHz passive RFID readers, tags, and their applications into existing bar-code based gate systems to improve the port logistics process, and we analyzed results of a pilot test in economic and non-economic perspectives. The main purpose of this study is to develop the RFID based automatic gate passing system in container terminals, and is to validate its economic and non-economic feasibility. In order to accomplish the purpose of this study, first, we examined previous researches on RFID technology acceptance in the port logistics industry, second, we Identified and analyzed the business process of existing gate systems in container terminals, third, we build RFID gate systems with 13.56Mhz tags, readers, and its middle-ware, finally we tested the system and its performance. The results were successful and showed the feasibility of the system in real container terminal gates. Economic and non-economic contribution was confirmed. Although the system has technological limitations with short range passive type, we clearly identified its potential capability and its economic validity in the field, which are the implications of this study.

In RFID system, the communicated data can be easily eavesdropped and tampered with by an attacker because the communication between the reader and the tag is performed in an insecure channel. Therefore, authentication is an important role in RFID applications for providing security and privacy. In 2006, Lee, Asano and Kim proposed an RFID mutual authentication protocol (the LAK protocol) which utilizes a hash function and synchronized secret information. However, Cao and Shen showed that the LAK protocol is vulnerable to replay attack, and therefore an adversary can impersonate the tag. This paper proposes a new simple two-round RFID mutual authentication (TRMA) protocol based on secure one-way hash function. As a result, the proposed TRMA protocol not only can prevent various attacks and but also provides communication efficiency since they mutually authenticate by performing two-round between RFID tag and RFID reader.
