针对RFID标签所有权转移协议中存在的数据完整性受到破坏、物理克隆攻击、去同步攻击等多种安全隐私问题,新提出一种基于物理不可克隆函数(PUF)的超轻量级RFID标签所有权转移协议—PUROTP.该协议中标签所有权的原所有者和新所有者之间直接进行通信完成所有权转移,从而不需要引入可信第三方,主要涉及的运算包括左循环移位变换(Rot(X,Y))和异或运算($\oplus$)以及标签中内置的物理不可克隆函数(PUF),并且该协议实现了两重认证,即所有权转移之前的标签原所有者与标签之间的双向认证、所有权转移之后的标签新所有者与标签之间的双向认证.通过使用BAN(Burrows-Abadi-Needham)逻辑形式化安全性分析以及协议安全分析工具Scyther对PUROTP协议的安全性进行验证,结果表明该协议的通信过程是安全的,Scyther没有发现恶意攻击,PUROTP协议能够保证通信过程中交互信息的安全性及数据隐私性.通过与现有部分经典RFID所有权转移协议的安全性及性能对比分析,结果表明该协议不仅能够满足标签所有权转移过程中的数据完整性、前向安全性、双向认证性等安全要求,而且能够抵抗物理克隆攻击、重放攻击、中间人攻击、去同步攻击等多种恶意攻击.在没有额外增加计算代价和存储开销的同时克服了现有方案存在的安全和隐私隐患,具有一定的社会经济价值. 相似文献

RFID标签在所有权转移过程中面临安全和隐私泄露的风险。针对这一问题,提出了一种带有转移开关并基于Hash函数的新型标签所有权转移协议。原所有者和新所有者分别拥有不同的通信密钥,前者的密钥用于原所有者与标签之间的认证,后者的密钥用于标签与新所有者之间的所有权转移。由于存在转移开关(Ownership Transfer Switch,OTS),因此可以通过对OTS的设置来实现抵抗去同步化攻击。对该协议的安全性分析结果表明,该协议能够满足标签所有权转移的安全需要,并能抵抗常见的主被动攻击,使标签的所有权实现完全转移。最后对协议进行了性能分析,结果表明所提协议在效率性能方面比已有的RFID标签所有权转移协议有明显提高。 相似文献

通用可组合安全的RFID标签组所有权转移协议 总被引:1,自引:0,他引:1
在某些应用中,往往需要在一次会话中同时完成一组RFID标签所有权的转移.然而,现有的标签组所有权转移方案大多需要可信第三方的支持且存在诸多安全和隐私保护问题.在分析安全需求的基础上,设计了一个安全高效的RFID标签组所有权转移协议.该协议在无可信第三方支持的情况下实现了一组标签所有权的同时转移.在通用可组合框架下,定义了RFID标签组所有权转移的理想函数,并证明新协议实现了所定义的理想函数.与已有同类协议相比,新协议不仅具备匿名性、不可追踪性、授权访问、抗异步攻击、前向隐私保护、后向隐私保护等安全和隐私属性,还具有通用可组合安全性.在性能方面,新方案的计算复杂度相对较低,且交互次数和标签端存储量也较少. 相似文献

一种新的RFID标签所有权转移协议 总被引:2,自引:0,他引:2
针对无线射频识别( RFID)技术标签在生命周期内安全转移其所有权的问题,提出一个不依赖可信第三方参与转移的、基于Hash函数的RFID标签所有权转移协议。采用挑战响应机制,使用Status标志位来标识标签当前所有权归属。其中新旧所有者分别与目标标签共享不同的密钥,并与其传递通信数据来认证参与转移实体的身份,从而认证新所有者获得目标标签的所有权。分析结果表明,该协议满足标签所有权转移的安全需求,目标标签在执行协议后为新所有者所有,实现了所有权的排他转移,在安全性和效率方面较已有RFID标签转移协议有较大提高。 相似文献

针对现有无线射频识别群组标签所有权转移协议中出现的后向隐私泄露、暴力破解等安全问题,提出一种改进的所有权转移协议。通过字合成、循环移位简单位运算加密随机数,以抵抗攻击者的暴力破解攻击。利用可信第三方的参与,在不经过原所有者的条件下直接向新所有者和标签下发初始密钥,进而同步更新密钥,保证协议的后向隐私安全性。使用标签所有权归属标识位定义群组标签归属权,防止出现双重所有权,同时给出协议的GNY逻辑证明。分析结果表明,该协议具有安全、低成本特性。 相似文献

针对射频识别(RFID)标签认证及其所有权转移过程的隐私泄露等安全问题,以及认证协议通常与标签所有权转移协议单独设计的现状,基于支持椭圆曲线加密(ECC)的标签,提出了一个适用于开放环境的兼具标签认证和所有权转移的协议。该协议结构类似于Diffie-Hellman密钥交换算法结构,协议的标签隐私保护基于椭圆曲线上的计算性Diffie-Hellman问题的难解性。经证明,该协议满足标签隐私保护要求及认证协议的其他安全需求。与近年来其他基于标签支持ECC的RFID认证协议相比,从支持标签所有权转移、标签计算开销、协议通信开销和标签隐私保护等多方面综合评估,所提出的认证协议优于对比协议。另外,针对较安全的应用场合,给出了阅读器单向认证标签的简化版协议。 相似文献

Security standards for the RFID market 总被引:1,自引:0,他引:1
As the RFID market expands, we'll see the continued proliferation of RFID tags built for highly specialized vertical markets, which means greater variety and the consequent need to ensure interoperability. A great deal of research and development is currently under way in the RFID security field to mitigate both known and postulated risks. Manufacturers; business managers, and RFID systems engineers continue to weigh the trade-offs between chip size, cost, functionality, interoperability, security and privacy with the bottom-line impact on business processes. Security features supporting data confidentiality, tag-to-reader authentication, optimized RF protocols, high-assurance readers, and secure system engineering principles should become available. Security and privacy in RFID tags aren't just technical issues; important policy questions arise as RFID tags join to create large sensor networks and bring us closer to "ubiquitous computing." With public attention focused on the RFID landscape, security and privacy have moved to the forefront in RFID standards work, and the results are worth watching. 相似文献

Since RFID tags are ubiquitous and at times even oblivious to the human user, all modern RFID protocols are designed to resist tracking so that the location privacy of the human RFID user is not violated. Another design criterion for RFIDs is the low computational effort required for tags, in view that most tags are passive devices that derive power from an RFID reader's signals. Along this vein, a class of ultralightweight RFID authentication protocols has been designed, which uses only the most basic bitwise and arithmetic operations like exclusive-OR, OR, addition, rotation, and so forth. In this paper, we analyze the security of the SASI protocol, a recently proposed ultralightweight RFID protocol with better claimed security than earlier protocols. We show that SASI does not achieve resistance to tracking, which is one of its design objectives. 相似文献

Privacy and security concerns inhibit the fast adaption of RFID technology for many applications. A number of authentication protocols that address these concerns have been proposed but real-world solutions that are secure, maintain low communication cost and can be integrated into the ubiquitous EPCglobal Class 1 Generation 2 tag protocol (C1G2) are still needed and being investigated. We present a novel authentication protocol, which offers a high level of security through the combination of a random key scheme with a strong cryptography. The protocol is applicable to resource, power and computationally constraint platforms such as RFID tags. Our investigation shows that it can provide mutual authentication, untraceability, forward and backward security as well as resistance to replay, denial-ofth-service and man-in-the-middle attacks, while retaining a competitive communication cost. The protocol has been integrated into the EPCglobal C1G2 tag protocol, which assures low implementation cost. We also present a successful implementation of our protocol on real-world components such as the INTEL WISP UHF RFID tag and a C1G2 compliant reader. 相似文献

RFID systems have been widely adopted in various industrial as well as personal applications. However, traditional RFID systems are limited to address only one tag for each application object. This limitation hinders the usability of RFID applications because it is difficult, if not impossible, to distinguish many tags simultaneously with existing RFID systems. In this paper, we propose a new RFID tag structure to support multiple-objects that can be easily shared by many different RFID applications. That is, the proposed RFID tag structure supports that a tag maintains several different objects and allows those applications to access them simultaneously. We also propose an authentication protocol to support multiple-object RFID applications. Especially, we focus on the efficiency of the authentication protocol by considering different security levels in RFID applications. The proposed protocol includes two types of authentication procedures. In the proposed protocol, an object has its security level and goes through one of different authentication procedures suitable for its security level. We report the results of a simulation to test the performance of the proposed scheme. In our simulation, we considered the safety of our scheme against potential attacks and evaluated the efficiency of the proposed protocol. 相似文献

Radio frequency identification (RFID) technology has recently aroused great interest due to its convenience and economic efficiency. Through RFID become popular worldwide, it is susceptible to various attacks and security problems. Since RFID systems use wireless transmission, user privacy may be compromised by malicious people intercepting the information contained in the RFID tags. Many of the methods previously proposed to prevent such attacks do not adequately protect privacy or reduce database loading. In this paper, we propose a new authentication and encryption method that conforms to the EPC Class 1 Generation 2 standards to ensure RFID security between tags and readers. Our scheme not only reduces database loading, but also ensures user privacy. Finally, we survey our scheme from several security viewpoints, and prove its feasibility for use in several applications. 相似文献

In many real world applications, there is a need to search for RFID tagged items. In this paper, we propose a set of protocols
for secure and private search for tags based on their identities or certain criteria they must satisfy. When RFID enabled
systems become pervasive in our life, tag search becomes crucial. Surprisingly, the problem of RFID search has not been widely
addressed in the literature. We analyzed the privacy and security features of the proposed tag search protocols, and concluded
that our protocols provide tag identity privacy, tag source location privacy, and tag-reader communication privacy. For the
first time, we propose a formal method to securely search RFID tags which satisfy certain search criteria. 相似文献
