ECC-based lightweight authentication protocol with untraceability for low-cost RFID

Due to the potential wide deployment of Radio Frequency Identification (RFID), the security of RFID systems has drawn extensive attention from both academia and industry, and the RFID authentication protocol is an important mechanism in the security of RFID systems. The desired security requirements of RFID authentication protocols include privacy, integrity, authentication, anonymity/untraceability, and even availability. To design an efficient protocol that satisfies all the requirements with limited resources is a challenge. This paper proposes a new RFID authentication protocol based on Error Correction Codes (ECC). The proposed scheme has excellent performance in terms of security, efficiency, server’s maintenance, robustness, and cost. The tag only performs simple operations, such as random number generation and simple bitwise computations. The lightweight feature makes it attractive to those low-cost RFIDs that support only simple operations.     

Anti-cloning protocol suitable to EPCglobal Class-1 Generation-2 RFID systems

Radio frequency Identification (RFID) systems are used to identify remote objects equipped with RFID tags by wireless scanning without manual intervention. Recently, EPCglobal proposed the Electronic Product Code (EPC) that is a coding scheme considered to be a possible successor to bar-code with added functionalities. In RFID-based applications where RFID tags are used to identify and track tagged objects, an RFID tag emits its EPC in plaintext. This makes the tag inevitably vulnerable to cloning attacks as well as information leakage and password disclosure. In this paper, we propose a novel anti-cloning method in accordance with the EPCglobal Class-1 Generation-2 (C1G2) standard. Our method only uses functions that can be supported by the standard and abides by the communication flow of the standard. The method is also secure against threats such as information leakage and password disclosure.

WSN集成EPCglobal:环境感知的供应链监管

随着目前全球供应链管理网络体系（EPCglobal）的日趋成熟,供应链的管理已经不再局限于一个企业内部,开放式、多角色参与的供应链管理模式正在形成。通过物品上的EPC标识和一个分布式的信息系统,EPCglobal为流通物品创建了一条信息链,可追溯至此物品的供应链源头。从供应链管理的本质与发展趋势看,与真实环境的交互能力越强,交互数据越实时,越能更好地对供应链的实施全程监管。提出一个将WSN与EPCglobal的集成方案,无缝地绑定物品EPC标识和环境感知信息,可大大增强EPCglobal对生产和仓储过程的信息获取和处理能力,并提供统一接口供用户访问。WSN与EPCglobal的集成不仅是技术意义上的异种网络集成,更是对供应链信息化管理层面的一种拓宽和深化。

Web services reengineer RFID system

EPCglobal combines RFID system and Web services to construct EPCglobal Network. Web services are going to reengineer RFID system from its initial closed-cycle application to the current open public service. The starting point is an overview of the framework of EPCglobal Network, which provides a public service, and details on five components function. After that, two main technologies are presented in ECPglobal Network and the equivalent technologies are analyzed in Web services. Finally, a practical instance of application in shipment is illustrated.

射频识别防碰撞Q算法的分析及改进

为了减少射频识别系统多个标签防碰撞过程中所消耗的动态功耗,通过对RFID领域超高频频段EPCglobal Class-1Gen-2标准中的标签识别层所采用的防碰撞技术及相关指令的分析,在其基础上对Q算法提出改进方案。该方案使用稳定缓变的帧长度来适应现场标签数量,使帧长度保持在最优值,减小标签内部门电路翻转频率,从而降低了标签防碰撞过程中总动态功耗81.8%。仿真实验结果表明,改进后的Q算法帧长度调整频率低于改进前的Q算法帧长度调整频率。
