JPMP SID Tag is the security senor tag to provides physical information protective function using sensor module, has impossible feature to copy and fake the data which is stored in the tag. So data which is stored in the JPMP SID Tag has authenticity, integrity, originality. Therefore JPMP SID Tag could be applied in the place where the security of data is demanded. This paper propose the system using the JPMP SID Tag to acquire and protect digital evidence where cause investigation of accident is necessary. Also, proposed systems is complement of software security with composition secondary control logic for JPMP SID tag access control.

A fully integrated CMOS security-enhanced passive (SEP) tag that compensates the security weakness of ISO/IEC 18000-6C is presented in this paper. For this purpose, we propose a security-enhanced protocol that provides mutual authentication between tag and reader. We show that the proposed protocol meets the security demands of the ongoing international standard for RFID secure systems, ISO/IEC 29167-6. This paper fabricates the SEP tag with a 0.18-${\mu}m$ CMOS technology and suggests the optimal operating frequency of the CMOS SEP tag to comply with ISO/IEC 18000-6C. Furthermore, we measure the SEP tag under a wireless environment. The measured results show that communications between the SEP tag and reader are successfully executed in both conventional passive and SEP modes, which follow ISO/IEC 18000-6C and the proposed security enhanced protocol, respectively. In particular, this paper shows that the SEP tag satisfies the timing link requirement specified in ISO/IEC 18000-6C.

This paper describes a passive SID sensor tag that provide physical security functions based on a sensor interface module. It elementarily consists of a serial I/O interface, control module, and sensor module. In this paper, it show tamper-proof security functions by comparison and encryption with the sensor signal data using the physical resistors. The passive SID sensor tag can be realized by the real time management for the safety, forgery, and so on. The proposed SID tag embedded with a sensor module is expected to find wide physical security applications.

Most of the sources of security and privacy issues in RFID technology arise from the violation of the air interface between a tag and its reader. This paper will approach the security risk analysis is process from the perspective of the RFID tag life cycle, identify the tag usage processes, identify the associated vulnerability and threat to the confidentiality, integrity and availability of the information assets and its implications for privacy, and then mitigate the risks.

This study, in particular, aims to regulate the core techniques of ubiquitous computing, such as the use of an ad hoc network and the smart-tag technique, and to look more closely into RFID Tag's smart-tag-related security service. The study aims to do so because several important technical factors and structures must be taken into account for RFID Tag to be applied in the ubiquitous-computing-related infrastructure, and the security of the tag is considered one of the core technologies. To realize secure ubiquitous computing in the case of the Passive-tag-Performing RF communication, a less costly security service, the technical items needed to carry this out, a security service to be applied to passive tags, and network management techniques are required. Therefore, the passive-tag-based networks as the authentication level is established based on the secure authentication of each tag and the service that the tag delivers in the passive-tag-based networks and as the same service and authentication levels are applied, and the active-tag-based network system proposed herein is not merely a security service against illegal RFID tags by performing a current-location and service registration process after the secure authentication process of the active RFID tag, but is also a secure protocol for single and group services, is proposed in this study.

We propose a method to protect the tag's information from illegal reader in RFID system. In this method, a special tag called ownership tag makes intentionally collisions during singulation. By the forced collision of an ownership tag a reader can obtain the information of ordinary tags. Whereas a reader can not find my information on tag's ID without the ownership tag.

Recently, study on RFID Tag Searching technique which is used to find a specific tag in particular tag group were developed continuously. RFID tag searching technique can be applicate in various fields such as product management, finding children, and electronic anklet. To implement a RFID tag search system, RFID tag searching protocol should be considered various security threats such as reader and tag tracking, privacy, etc. For implementing a safe RFID tag lookup system, it is important to consider the potential security threats such as the tag tracking problem, and the privacy of the owner of the tag reader problem. There exists an RFID tag lookup system that satisfies a few security requirements, but the privacy of the owner of the tag reader problem has still been left unsolved, and even if it were solved, it requires a considerable amount of cryptographic operations to be performed which results in a decrease in performance. This paper proposes a system that does not degrade the performance while solving the privacy of the owner of the tag reader problem.

Radio Frequency Identification(RFID) has been considered as an key infrastructure for the ubiquitous society. However, due to the inherent drawbacks, RFID causes var- ious security threats like privacy problems, tag cloning, etc. This paper analyses the security risk analysis process from the perspective of the RFID tag life cycle, identify the tag usage process, identify the associated vulnerability and threat to the confidentiality, integrity and availability of the information assets and its implications for privacy, and the mitigate the risks.

A passive RFID tag which received attention as a future technology for automatic and quick identification faces some difficulties about security problems such as tag authentication, reader authentication, data protection, and untraceability in addition to cost and reliable identification. A representative passive RFID technology is the ISO/IEC 18000-6 Type C which is an international standard for 900 MHz UHF-band. This standard has some difficulties in applying to the security services such as originality verification, tag's internal information protection, and untraceability, because it does not provide high-level security solution. In this paper, we summarize security requirements of ISO/IEC ITC 1/SC 31 international standardization group, propose security protocols suitable for the UHF-band passive RFID system using a crypto engine, and analyze its security strength. In addition, we verify that it is possible to implement a tag conforming with the proposed security protocols by presenting concrete command/response pairs and cryptographic method.
