With the development and prospects of intelligent networks, the Internet of Things is becoming increasingly popular. It aims to utilize network edges to achieve intelligent services and evaluation of the Internet of Things. In addition, this utilization enhances the user experience, and ensures service resilience in the face of any disaster scenario. IoT devices deploy distributed structures that are more responsive, with better quality of service and proximity to end users.Nevertheless, security is primarily considered to be the sensitivity to resist attacks. This work aims to introduce a new secure routing model, it chooses and encrypts by the best path. Firstly, the optimal path or node is selected for secure transmission while performing the optimal link-state multiplexing route.To optimize path selection for destination and source, encryption is performed to ensure secure transmission. In this study, an improved WOA algorithm (IWOA) for security authentication was proposed.The simulation results show that the IWOA protocol not only chooses a safer path but also has fewer hops on average, so that the nodes have more energy left on average and energy consumption is more uniform. In addition, the IWOA protocol has a higher average packet loss rate, which means that it is faster than the WOA protocol in excluding malicious nodes from the network. In the face of wormhole attacks, the WOA protocol is powerless, but the IWOA protocol can quickly reduce the trust value of the wormhole and expel it from the network.
