Title:
Secure and Lightweight User Authentication Scheme for Cloud-Aided Internet of Things
Authors: Chenyu Wang, Ding Wang, Yihe Duan, Xiaofeng Tao
Abstract:The cloud-aided Internet of Things (IoT) overcomes the resource-constrained nature of the traditional IoT and develops rapidly in such fields as smart grid and intelligent transportation. In a cloud-aided IoT system, users can remotely control the IoT devices or send specific instructions to them. When the user’s identity is not verified and an adversary delivers malicious instructions to IoT devices, the system’s security may be compromised. Besides, the real-time data stored in IoT devices can also be exposed to illegal users, causing security issues. Thus, the authentication mechanism is indispensable. Furthermore, with the exponential growth of interconnected devices, a gateway may connect to mass IoT devices. The efficiency of authentication schemes is easily affected by the computation power of the gateway. Although recent research has proposed many user authentication schemes for IoT, only a dozen schemes are designed for cloud-aided IoT. Therefore, we take a typical scheme (presented at IEEE TDSC 2020) as an example to capture user authentication schemes’ common weaknesses and design challenges for cloud-aided IoT. Then, we propose a new secure user authentication scheme for cloud-aided IoT with lightweight computation on gateways. The proposed scheme provides secure access between the remote user and IoT devices with many ideal attributions, such as forward secrecy and multi-factor security. Meanwhile, the security of this scheme is proved under the random oracle model, heuristic analysis, the ProVerif tool and BAN logic. Finally, we compare the proposed scheme with eleven state-of-the-art schemes in security and performance. The results show that the proposed scheme achieves all listed twelve security requirements with minimum computation and storage costs on gateways.
