The Internet of Things has become the third wave of the information industry and cloud computing, big data, and Internet technologies. Among the many identification technologies used in the Internet of Things, radiofrequency identification technology is undoubtedly one of the most popular methods today. It is replacing the traditional contact IC card and becoming a new trend of smart cards. At the same time, a large amount of data is generated in the IoT environment. A lot of data involve user privacy, and users do not have good control over these data. Collecting and utilizing these data on the basis of protecting user privacy have become an important problem to be solved urgently. With the implementation of the strategy of rejuvenating the country through science and education, major colleges and universities are developing rapidly through enrollment and expansion, which also brings inconvenience to campus security management. Although the traditional campus all-in-one card system can guarantee the security identity of people entering and leaving, it does not reasonably integrate and utilize this information, resulting in waste of information resources and, to a certain extent, the problem of user privacy leakage. To solve the above problems, a new system was developed to integrate resources to identify users. To protect the privacy data of Internet of Things users, a specific solution using blockchain technology is proposed; for the identity authentication problem of Internet of Things users, the identity authentication based on the public key address of the blockchain is used on the chain, and the group signature is used off the chain. The identity authentication method solves the contradiction between anonymity and traceability in blockchain application scenarios. The simulation results show that the system not only considers user privacy but also has extremely important practical significance for the promotion of Internet of Things and RF applications.
物联网已成为继云计算、大数据和互联网技术之后的信息产业的第三次浪潮。在物联网中使用的众多识别技术中，射频识别技术无疑是当今最流行的方法之一。它正在取代传统的接触式 IC 卡，成为智能卡的新趋势。同时，物联网环境中会产生大量数据。大量数据涉及用户隐私，用户对这些数据没有很好的控制。在保护用户隐私的基础上收集和利用这些数据已成为亟待解决的重要问题。随着科教兴国战略的实施，各大高校通过招生和扩招迅速发展，这也给校园安全管理带来了不便。虽然传统的校园一卡通系统可以保证进出人员的安全身份，但没有合理地整合和利用这些信息，造成信息资源的浪费，在一定程度上存在用户隐私泄露的问题。为了解决上述问题，开发了一个新的系统来整合资源以识别用户。为了保护物联网用户的隐私数据，提出了一种使用区块链技术的特定解决方案；对于物联网用户的身份认证问题，在链上使用基于区块链公钥地址的身份认证，并在链下使用群签名。该身份认证方法解决了区块链应用场景中匿名性和可追溯性之间的矛盾。仿真结果表明，该系统不仅考虑了用户隐私，而且对物联网和射频应用的推广具有极其重要的现实意义。
