With the widespread application of the Internet of Things, millions of sensors, actuators, or embedded electronic devices are interconnected through the Internet. Monitoring a large number of IoT devices is a huge challenge, especially when sensor nodes are limited (such as limited CPU, memory, and batteries). The IoT device management protocol has become an important research field. However, currently, management protocols designed for the Internet of Things, such as CoAP and MQTT, do not provide security support. SNMP is a widely used protocol for monitoring systems, and its v3 version provides comprehensive security support. However, SNMPv3 uses complex encryption algorithms and cannot be applied to resource limited IoT devices. In order to address this issue, we propose a secure and lightweight implementation scheme for Internet of Things (IoT) device management based on the ZUC algorithm. This solution utilized the ZUC algorithm as its core and created authentication and encryption protocols in order to provide safe connection and control ofloT devices. We conducted simulation experiments and compared our scheme with the simple network management protocol to confirm its viability. The results show that, while maintaining security, the proposed solution greatly lowers computing and communication overhead, making it suitable for Internet of Things (IoT) scenarios.
