Interest in IoT technology is increasing these days, and core of IoT technology is sensor network technology. Although ZigBee network is widely used in IoT-sensor network, it is vulnerable to various security threats such as wiretapping of sensor information, abnormal packet flow, data forgery and denial of service attack. However, ZigBee IoT-sensor networks should operate in resource environments with limited computing capabilities. Therefore, it is imperative that IoT-sensor network security technologies be researched for lightweight design. In this paper proposed an algorithm for mutual authentication of IoT-sensor networks based on a trust assessment model that enables safe IoT-sensor network construction even with small security operations. The proposed trust-based authentication algorithm is designed with direct trust relationships between ZC-Sensor nodes belonging to the ZigBee Pico-Net and performs a trust assessment between nodes based on probability calculation and logic calculation. In addition, the proposed mutual authentication algorithm can support confidentiality, anonymity, mutual authentication and freshness in terms of security safety of the IoT-sensor network and increase the lightweight-ness of the existing authentication methods. And it will be possible to extend safety and survival period of IoT-sensor network by reducing the use of limited batteries in sensor nodes. |
