This paper introduces development of a Military Entrance Control System using the developed military insignia UHF RFID tags. Generally, in the military entrance control system, the security identification (ID) card with HF RFID tag can be used, to increase the security level, the developed insignia UHF RFID tags are used in the enforced military entrance control system. The general metal insignias, have been worn on a hat or on the shoulder pads of a military uniforms, are simulated and developed as UHF RFID insignia tags. The military entrance control system can manage the name, rank, address (information of military personnel), time and date of entrance and the history of entrance of the security area.

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.

With the rapid progress of RFID security technologies, the international standard group ISO/IEC JTC 1/SC 31 is developing a few security technologies for RFID systems. One of the initial proposals is ISO/IEC working draft (WD) 29167-6. Recently, Song and others stated that Protocol 1 of ISO/IEC WD 29167-6 is vulnerable to a malicious adversary. However, their analysis comes from a misunderstanding regarding a communication parameter called Handle. In this letter, we point out that an adversary cannot obtain any sensitive information from intervening in Protocol 1.

Recently as increasing the use of mobile communication devices the use of mobile readers for recognition tag attached to objects is also increasing. Accordingly, meantime, that gives rise to the vulnerability of RFID systems between reader and tag security issues, as well as security issues between the reader and the back-end server will occur. In this paper between the reader and the back-end server to security vulnerabilities efficient authentication protocol using the hash function is proposed.

Spotlighted as an innovative information technology environment, ubiquitous computing has been actively researched on recently. Especially, domestic and global researches focus on the RFID system, which is being eyed to replace the existing bar-code system. As an essential technology for ubiquitous computing, the RFID system can be applied for various purposes. The security issues of the RFID system focus on how the low-priced tag type could have reasonable price competitiveness. The Auto-ID Center in the U.S. is spearheading the research on distribution service and omni-directional security. As for Japan, the researches on omni-directional security and EPC application are necessary in securing the technology for ubiquitous computing with support from the Ministry of Public Management Home Affairs, Posts, and Telecommunication. In this paper, a method of ensuring the availability of the RFID system service will be presented based on the ubiquitous computing environment with the existing omni-directional security and user-friendly interface. While the existing researches focus on the RF reader system and tag-based security, this paper's suggestion also considers the availability of a sen ice to suggest ways of increasing the practical usage of a low-priced RF tag.

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.

RFID/USN is important infrastructure of the ubiquitous society. And so, It is various and practical research is attempted. These two base technology have physical characteristic and complement relationship. Like this relationship is applied Following example that is system research which manages warehouse stocks and conditions. First, We adhere RFID Tag at the Pallet of the warehouse and do identification goods. And then, It grasps the environment state information of stocks with sensor module which has Zigbee wireless communication function. From like this process RFID Tag information and jop-control command of sensor node also it is exposed to air. Therefore, We control sensor node in USN/RFID environment through the mobile device. And system design for the security Apply of the process is main purpose of this paper's. We propose the condition and function of the mobile device to the secondary. And We define the relation of the sensor node with RFID to be arranged to a warehouse. Finally, This paper is designed to find a trade-off of the following viewpoints. First, We offer suitable sensor-control information to a actual manager. Second, We offer RFID tag security approach to control the action of the sensor. Third, It increases the survivability of sensor node form.

The creation of a RFID/USN environment has increased rapidly due to the activation of ubiquitous security environment suitable for RFID/USN environment but has failed to comply with the speed of security threats. Therefore, this thesis presents MSNR suitable for RFID/USN. The MSNR presented showed an increase in the processing rate of 1.3 times compared to the existing AES and showed 2 fold improvement in performance in terms of the overall system efficiency. Therefore, MSNR is considered to be a password algorithm suitable to overcome the conditions of environmental resource conditions, such as RFID/USN.

The RFID system provides undeniable advantages so that it is used for various application. However recent RFID system is vulnerable to some attacks as eavesdropping, replay attack, message hijacking, and tag tampering, because the messages are transmitted through the wireless channel and the tags are cheap. Above attacks cause the tag and reader impersonation, denial of service by invalidating tag, and the location tracking concerning bearer of tags, A lot of RFID authentication protocol bas been proposed to solve the vulnerability. Since Weis, Sanna, Rivest, and Engel, proposed the bash-based RFID authentication protocol, many researchers have improved hash-based authentication protocol and recent bash-based authentication protocols provide security and desirable privacy. However, it remains open problem to reduce the tag identification time as long as privacy and security are still guaranteed. Here we propose a new protocol in which the tags generate the message depending on the state of previous communitions between tag and reader. In consequence, our protocol allows a server to identify a tag in a reasonable amount of time while ensuring security and privacy, To be specific, we reduced the time for the server to identify a tag when the last session finished abnormally by at least 50% compared with other bash-based schemes that ensure levels of security and privacy similar to ours.
