设计安全的无线射频识别协议有助于实现智慧城市的规划和构建完善的智慧网络。安全的RFID所有权转移协议要求同时具备安全性和隐私性,标签的前向不可追踪性和后向不可追踪性是RFID系统实际应用中需要考量的两个重要的隐私性能。针对现有供应链系统中所有权转移协议存在的各种安全隐私问题,该文改进了原有前向不可追踪性定义的错过密钥更新过程的不合理的假设,提出了强前向不可追踪性的概念。提出了一个基于二次剩余定理的轻量级RFID所有权转移协议,并使用改进的模型和定义形式化证明了协议的安全性和隐私性。证明结果表明新方案既可以抵御内部读卡器恶意假冒攻击,追踪攻击,标签假冒攻击和异步攻击,又满足强前向不可追踪性和后向不可追踪性等隐私性能;新协议在实现低成本和高效率认证的基础上,比其他协议安全性和隐私性更好。 相似文献

一种具有阅读器匿名功能的射频识别认证协议 总被引:1,自引:0,他引:1
在射频识别(RFID)的应用中,安全问题特别是用户隐私问题正日益凸显。因此,(用户)标签信息的隐私保护的需求越来越迫切。在RFID系统中,标签的隐私保护不仅是对外部攻击者,也应该包括阅读器。而现有许多文献提出的认证协议的安全仅针对外部攻击者,甚至在外部攻击者的不同攻击方法下也并不能完全保证安全。该文提出两个标签对阅读器匿名的认证协议:列表式RFID认证协议和密钥更新式RFID认证协议。这两个协议保证了阅读器对标签认证时,标签的信息不仅对外部攻击者是安全的而且对阅读器也保持匿名和不可追踪。相较于Armknecht等人提出的对阅读器匿名和不可追踪的认证协议,该文所提的协议不再需要增加第三方帮助来完成认证。并且密钥更新式RFID匿名认证协议还保证了撤销后的标签对阅读器也是匿名性和不可追踪的。 相似文献

One of the recent realms that gathered attention of researchers is the security issues of Radio Frequency Identification (RFID)
systems that have tradeoff between controlled costs and improved efficiency. Evolvement and benefits of RFID technology signifies
that it can be low-cost, efficient and secured solution to many pervasive applications. But RFID technology will not intermingle
into human lives until prevailing and flexible privacy mechanisms are conceived. However, ensuring strong privacy has been
an enormous challenge due to extremely inadequate computational storage of typical RFID tags. So in order to relieve tags
from responsibility, privacy protection and security assurance was guaranteed by central server. In this paper, we suggest
serverless, forward secure and untraceable authentication protocol for RFID tags. This authentication protocol safeguards
both tag and reader against almost all major attacks without the intervention of server. Though it is very critical to guarantee
untraceability and scalability simultaneously, here we are proposing a scheme to make our protocol more scalable via ownership
transfer. To the best of our knowledge this feature is incorporated in the serverless system for the first time in pervasive
environments. One extension of RFID authentication is RFID tag searching, which has not been given much attention so far.
But we firmly believe that in near future tag searching will be a significant issue RFID based pervasive systems. So in this
paper we propose a serverless RFID tag searching protocol in pervasive environments. This protocol can search a particular
tag efficiently without server’s intervention. Furthermore they are secured against major security threats. 相似文献

Radio Frequency Identification (RFID) Technology is a contactless automatic identification technology using radio frequency.
For this RFID technology to be widely spread, the problem of privacy invasion should be solved. There are many research works
in progress to solve the RFID privacy problems. Most of works for solving this problem have focused on developing light-weight
cryptographic modules which can be embedded into RFID tags, but some of them used a proxy agent approach that control communications
between the tag and the reader for protecting user privacy. The later approach is very useful and practical in terms of manufacturing
low-cost tag hardware. However, all schemes of this approach have some problems in ownership transfer and forgery detection.
In this paper, we are focusing on the proxy agent approach and we suggest an advanced agent scheme that guarantees not only
privacy protection but also forgery detection. And our scheme is more scalable than other agent schemes so far. 相似文献

The radio frequency identification (RFID) technology has been widely used so far in industrial and commercial applications. To develop the RFID tags that support elliptic curve cryptography (ECC), we propose a scalable and mutual authentication protocol based on ECC. We also suggest a tag privacy model that provides adversaries exhibiting strong abilities to attack a tag’s privacy. We prove that the proposed protocol preserves privacy under the privacy model and that it meets general security requirements. Compared with other recent ECC-based RFID authentication protocols, our protocol provides tag privacy and performs the best under comprehensive evaluation of tag privacy, tag computation cost, and communications cost. 相似文献

Radio Frequency Identification (RFID) is a relatively new technology. In recent years, it has been shown to be convenient and feasible in many applications. However, there are security issues which need to be addressed. Due to the wireless transmission of the RFID system, malicious people can gain the information in the RFID tags, and the user’s privacy is invaded. Although there have been many protection methods proposed for RFID security, the system has remained vulnerable to various attacks. In this paper, we propose a conforming of the EPCglobal Class 1 Generation 2 standards RFID ownership transfer protocol with provable security. The proposed scheme can resist several attacks and ensure a secure transaction. 相似文献

Radio frequency identification (RFID) is a wireless technology used in various applications to minimize the complexity of everyday life. However, it opens a large number of security and privacy issues that require to be addressed before its successful deployment. Many RFID authentication protocols are proposed in recent years to address security and privacy issues, and most of them are based on lightweight cryptographic techniques such as pseudo-random number generators (PRNGs), or bitwise logical operations. However, the existing RFID authentication protocols suffer from security weaknesses, and cannot solve most of the security and privacy problems. A new solution is necessary to address security and privacy issues. In this paper, an improved three-pass mutual authentication protocol (ITPMAP) for low-cost RFID tags is proposed to offer an adequate security level for RFID systems. The proposed ITPMAP protocol uses one PRNG on the tag side and heavy-weighted cryptographic techniques (i.e., digital signature and password-based encryption schemes) on the back-end server side instead of lightweight cryptographic techniques to address the security and privacy issues. The ITPMAP protocol is secure against various attacks such as cloning, spoofing, replay, and desynchronization attacks. Furthermore, as a proof of concept, the ITPMAP protocol is adopted to propose the design of three real-life RFID systems; namely: Signing and Verification of Graduation Certificate System, issuing and verification of e-ticketing system, and charging and discharging of prepaid card system. The Unified Modeling Language is used to demonstrate the design of the proposed ITPMAP protocol and systems. Java language is used for the implementation of the proposed systems. In addition, the “Mifare Classic” tags and readers are used as RFID apparatuses for the proposed systems. 相似文献
