Token-Based Lightweight Authentication to Secure IoT Networks

The rapid growth of Internet of Things (IoT) technology offers huge opportunities and also brings many new challenges related to the authentication in (IoT) devices. Using passwords or pre-defined keys have drawbacks that limit their use for different (IoT) applications like smart hotel and smart office. In fact, they didn't provide temporary access to data in such reservation systems. Thus, authenticating users basing on password mechanism is not feasible. In this paper, we propose a new Token-Based Lightweight User Authentication (TBL UA) for (IoT) devices, which is based on token technique in order to enhance the robustness of authentication. Security analysis shows the security strength of the proposed scheme such as token security, Perfect Forward Secrecy (PFS), etc. In addition, the presented performance analysis shows that it is a strong competitor among existing ones for user authentication in (IoT) environments.
