【摘要】：隨著物聯(lián)網(wǎng)時代的到來，作為物聯(lián)網(wǎng)感知層中支撐技術之一的RFID技術也越來越受到各領域研究者的重視。在物聯(lián)網(wǎng)的感知層中，RFID技術的主要側(cè)重點就是識別，但是因其本身資源受限的特點，在一定程度上限制了該技術的發(fā)展。在未來的物聯(lián)網(wǎng)時代，對感知層中RFID技術的要求是：成本低，安全程度高。 物聯(lián)網(wǎng)時代中，安全問題將會進一步突顯出來，如何保證物聯(lián)網(wǎng)感知層中RFID系統(tǒng)的隱私安全對整個物聯(lián)網(wǎng)的發(fā)展起著決定性的作用。而本論文主要著手點就是對物聯(lián)網(wǎng)時代中扮演主要角色的RFID技術的隱私安全問題進行研究。為了滿足該類低成本標簽的隱私安全，研究者提出了很多研究方案。其中基于LPN問題的HB家族協(xié)議在該領域受到研究者的青睞。 本論文研究主要分兩部分，第一部分分析了現(xiàn)有的基于LPN(噪聲環(huán)境下的學習校驗)問題的HB家族協(xié)議，這些協(xié)議分別從協(xié)議本身的算法設計、RFID標簽的硬件設計以及利用某些硬件上可簡單實現(xiàn)的手段增加攻擊者攻破的難度等手段，來逐漸的對HB家族協(xié)議進行改進。但是不管研究者如何改進HB協(xié)議，針對OOV提出的MIM攻擊類型，目前仍然沒有防護手段可以有效防止該類攻擊。本文就是在該研究基礎上，提出了在HB協(xié)議被攻破的基礎上，如何保證攻擊者不會追溯到RFID系統(tǒng)之前通信的相關信息，進而實行進一步的破壞。所以本論文提出前向隱私的HB協(xié)議，并從安全性和隱私性方面對新提出的協(xié)議進行了總結(jié)分析，分析顯示，新提出的HB協(xié)議確實起到了前向隱私安全的目的。 第二部分，本論文提出了另一種方法，在HB協(xié)議中引入旋轉(zhuǎn)因子和補償因子，分析結(jié)果表明，通過在RFID標簽中增加很小的存儲及計算，卻極大的提高了HB協(xié)議被攻破的難度。 在未來的物聯(lián)網(wǎng)時代，，如果發(fā)展RFID技術，需要更優(yōu)的硬件設計以及尋求更完善的存儲技術提高存儲容量，進而可以將目前公鑰基礎上的加密手段應用到RFID安全領域中。
[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.
