【摘要】：无线射频识别技术(Radio Frequency Identification, RFID)以其具有较强的抗干扰能力、可在恶劣环境中工作、储存传输信息量大及寿命长等独特优势,已被广泛应用于人们的日常生活及各种生产活动中。其中,基于RFID技术的供应链管理是RFID技术最重要的应用之一。供应链环境下,物品及其RFID标签的所有权在其生命周期内常常发生转移。由于RFID标签与读写器间的开放型无线环境,标签的计算、通讯和存储能力十分有限,使得标签与读写器在所有权转移过程中易受到窃听、重放、跟踪等安全隐私攻击,尤其是,在实际应用中,RFID标签常以群组方式发生所有权转移。而传统的RFID安全认证协议,以及一次只能转移单个标签所有权的RFID标签所有权转移协议已无法满足现有的实际应用需求。因此,如何实现群组RFID标签所有权的安全转移,并确保标签所有者的安全隐私,已成为决定RFID技术能否持续发展的关键技术问题之一。针对上述问题,论文做了如下工作：第一,针对RFID标签所有权转移过程中的安全隐私问题,以及标签常以群组方式发生所有权转移的特性,分析现有群组RFID标签所有权转移协议设计方案的不足。第二,基于可信第三方(TTP, trusted third party)对称密钥更新管理策略,仅采用简单加密哈希函数与轻量级对称加密算法,提出了一个新的安全群组RFID标签所有权转移协议SGOTP (Secure Group Ownership Transfer Protocol)。第三,基于GNY逻辑对协议SGOTP安全性进行形式化证明,并对其安全与效率性能进行理论分析。理论分析表明,SGOTP可在一次会话中同时转移多个标签所有权,能抗击相应安全隐私威胁并避免出现双重所有权,与同类协议相比,SGOTP具有更高的安全性和更低的标签计算复杂度。
[Abstract]:Radio Frequency Identification (RFID) has been widely used in people's daily life and various production activities because of its unique advantages such as strong anti-interference ability, working in harsh environment, large amount of storage and transmission information and long life.Among them, supply chain management based on RFID technology is one of the most important applications of RFID technology.In the supply chain environment, ownership of items and their RFID tags often occurs during their life cycle.Due to the open wireless environment between the RFID tag and the reader, the computing, communication and storage ability of the tag is very limited, which makes the tag and reader vulnerable to eavesdropping, replaying, tracking and other security and privacy attacks during the transfer of ownership.In practical applications, RFID tags often transfer ownership in the form of group.However, the traditional RFID security authentication protocol and the RFID tag ownership transfer protocol, which can only transfer the ownership of one label at a time, can no longer meet the actual needs of existing applications.Therefore, how to realize the secure transfer of ownership of group RFID tags and ensure the security and privacy of tag owners has become one of the key technical problems that determine the sustainable development of RFID technology.In view of the above problems, the thesis has done the following work:Firstly, aiming at the problem of security and privacy in the process of RFID tag ownership transfer, and the characteristics of tag ownership transfer in group mode, this paper analyzes the shortcomings of the existing group RFID tag ownership transfer protocol design scheme.Secondly, based on the trusted third part) symmetric key update management strategy, a new secure Group Ownership Transfer protocol, SGOTP secure Group Ownership Transfer protocol, is proposed based on simple cryptographic hash function and lightweight symmetric encryption algorithm.Thirdly, the protocol SGOTP security is formalized based on GNY logic, and its security and efficiency performance are analyzed theoretically.Theoretical analysis shows that SGOTP can transfer multiple tag ownership simultaneously in a single session, which can resist the corresponding security and privacy threats and avoid double ownership. Compared with the same protocol, SGOTP has higher security and lower tag computational complexity.
