Abstract

With the rapid development of Internet of Things (IoT) technology, smart home users can access and control smart devices remotely to enjoy convenient and efficient services. However, sensitive data collected by smart devices is vulnerable to attacks such as eavesdropping and simulation when transmitted through public channels. At the same time, the security of resource-constrained smart devices is low, and attackers may use the controlled devices to carry out malicious operations further. To address the aforementioned existing security issues, this paper proposes a lightweight user anonymous authentication scheme for resource-constrained smart home environments. At the same time, the security analysis is carried out to further prove the proposed scheme's security. Finally, the performance analysis between the proposed scheme and the existing similar schemes proves that the proposed scheme has advantages in calculation cost and safety characteristics.
