Abstract:

Smart home networks connect smart devices at home through IoT technology, allowing users to remotely view and control their devices. However, information transmission on insecure public networks will face various network threats. Therefore, it is necessary to research and design secure, efficient, and compliant authentication key negotiation protocols for smart home networks. In 2020, WAZID et al. proposed a lightweight authentication key agreement protocol for smart home networks. After security analysis and verification, this paper found that the protocol has the following problems: the scheme overly relies on the gateway node(GWN) of the smart home gateway node, resulting in low system robustness; this scheme stores user and device keys in GWN, but GWN faces privilege attacks and various external network attacks, making it not absolutely secure; this scheme did not consider user access control. This article proposed a new multi-factor authentication key agreement scheme based on Chebyshev chaotic map and Secure Sketch for smart home networks. From the security proof and simulation experiments, although the computational cost of the proposed scheme has increased, the security has been improved and the communication cost has been reduced.

Key words: smart home, secure sketch, multi-factor authentication, Chebyshev chaotic map, key agreement
