【摘要】：随着物联网时代的到来，作为物联网感知层中支撑技术之一的RFID技术也越来越受到各领域研究者的重视。在物联网的感知层中，RFID技术的主要侧重点就是识别，但是因其本身资源受限的特点，在一定程度上限制了该技术的发展。在未来的物联网时代，对感知层中RFID技术的要求是：成本低，安全程度高。 物联网时代中，安全问题将会进一步突显出来，如何保证物联网感知层中RFID系统的隐私安全对整个物联网的发展起着决定性的作用。而本论文主要着手点就是对物联网时代中扮演主要角色的RFID技术的隐私安全问题进行研究。为了满足该类低成本标签的隐私安全，研究者提出了很多研究方案。其中基于LPN问题的HB家族协议在该领域受到研究者的青睐。 本论文研究主要分两部分，第一部分分析了现有的基于LPN(噪声环境下的学习校验)问题的HB家族协议，这些协议分别从协议本身的算法设计、RFID标签的硬件设计以及利用某些硬件上可简单实现的手段增加攻击者攻破的难度等手段，来逐渐的对HB家族协议进行改进。但是不管研究者如何改进HB协议，针对OOV提出的MIM攻击类型，目前仍然没有防护手段可以有效防止该类攻击。本文就是在该研究基础上，提出了在HB协议被攻破的基础上，如何保证攻击者不会追溯到RFID系统之前通信的相关信息，进而实行进一步的破坏。所以本论文提出前向隐私的HB协议，并从安全性和隐私性方面对新提出的协议进行了总结分析，分析显示，新提出的HB协议确实起到了前向隐私安全的目的。 第二部分，本论文提出了另一种方法，在HB协议中引入旋转因子和补偿因子，分析结果表明，通过在RFID标签中增加很小的存储及计算，却极大的提高了HB协议被攻破的难度。 在未来的物联网时代，，如果发展RFID技术，需要更优的硬件设计以及寻求更完善的存储技术提高存储容量，进而可以将目前公钥基础上的加密手段应用到RFID安全领域中。
[Abstract]:With the advent of the Internet of things era, RFID technology, as one of the supporting technologies in the Internet of things perception layer, has been paid more and more attention by researchers in various fields. In the sensing layer of the Internet of things, the main focus of RFID technology is identification, but the development of RFID technology is limited to some extent because of its limited resource. In the future Internet of things era, RFID technology in perceptual layer requires low cost and high security level. In the age of Internet of things, security issues will be further highlighted. How to ensure the privacy security of RFID system in the Internet of things perception layer plays a decisive role in the development of the whole Internet of things. The main point of this paper is to study the privacy security of RFID technology which plays a major role in the Internet of things era. In order to satisfy the privacy security of this kind of low-cost tags, many research schemes have been proposed. The HB family protocol based on LPN problem is favored by researchers in this field. This thesis is divided into two parts. In the first part, we analyze the existing HB family protocols based on LPN. These protocols improve the HB family protocol gradually from the algorithm design of the protocol itself and the hardware design of RFID tag and the use of some simple hardware means to increase the difficulty of the attacker to break through. However, no matter how the researchers improve HB protocol and the MIM attack type proposed by OOV, there are still no protective measures to effectively prevent this attack. On the basis of this research, this paper puts forward how to guarantee that the attacker will not trace the relevant information of the RFID system before the attack of HB protocol, and further destroy it. Therefore, this paper proposes the HB protocol of forward privacy, and summarizes and analyzes the new protocol from the aspects of security and privacy. The analysis shows that the new HB protocol does play the purpose of forward privacy security. In the second part, this paper proposes another method, which introduces rotation factor and compensation factor into HB protocol. The analysis results show that by adding a small amount of storage and computation to RFID tag, the difficulty of breaking HB protocol is greatly improved. In the future Internet of things era, if RFID technology is developed, it needs better hardware design and more perfect storage technology to improve storage capacity, which can be applied to RFID security field.
