Trusted Tree-Based Trust Management Scheme for Secure Routing in Wireless Sensor Networks

Abstract

The unique characteristics of wireless sensor networks make them susceptible to the attacks. The secure scheme is considered in designing the routing protocol and algorithm. The cryptography and authentication secure technology can defend the external attacks but have no way to protect the network when the internal attacks occur. However, the trust management scheme with attack-resistance and robustness can efficiently detect the internal attack. On the condition of defending the attacks, it is also an issue that the trust management scheme aids routing algorithm to improve the security and performance. In this paper, we proposed a Trusted Tree-based trust management for secure routing in wireless sensor networks. The common attacks are firstly analyzed. And then the dynamic time window is designed in the distributed trust model with the detection of direct trust and indirect trust. Based on the trusted nodes, Trusted Tree is constructed. And the path quality of nodes in Trusted Tree is used as the gradient for routing. Finally, we add Trusted Tree-based trust management into the QoS based routing protocol and algorithm. Experimental results show that the QoS based routing algorithm with Trusted Tree has better performance and security.

Understanding Cyber Security In Health Sector

“…The authors of [65] suggest a lightweight encryption algorithm that can be run on FPGAs for WSNs. The effectiveness of the XTEA algorithm when employed in conjunction with the confused key was analyzed and compared to the performance of other classic lightweight encryption techniques [68] [77]. The authors of [66] suggest an ECC-based encryption scheme that makes use of homomorphism encryption.…”

“…They demonstrated the improvement in performance as well as the increase of security in comparison to other methods already in use [37] [41]. A full analysis of the many different authentication mechanisms for the internet of things was published in reference [68]. In the field of Internet of Things communications employing WSNs, they examined more than forty different authentication methods and algorithms.…”

“…The proposed system greatly improves security and prevents trustless and malicious nodes from becoming the cluster head. Zhi Hu, et al [21] analyzed the attacks and designed the dynamic time window for the distributed trust model with the detection of direct trust and indirect trust. Here, only trusted nodes are considered and constructed the trusted tree, which is based on the path quality of nodes which is used as the gradient for routing.…”
