Key Takeaway Key Takeaway: This paper proposes a trust-based dynamic key-distribution scheme for wireless sensor networks, ensuring security and reducing energy consumption in secure data transmission.
Abstract
Trust is an important issue when a wireless sensor network is used in the fields such as military surveillance and reconnaissance, emergency rescue, and intelligent residential district. Due to the restrictions of energy, resource, and computing power in the sensor nodes, the traditional secure solutions cannot be applied to the wireless sensor networks directly. In this paper, applying the concept of trusted computing, a trust-based dynamic key-distribution scheme is suggested. In this scheme, when a cluster head distributes the key for the communication among nodes in its cluster, based on the trust relations between the base station and cluster head and between the cluster head and sensor nodes, a trust chain is formed, which provides a secured path for the transmission of data. It can be shown that this solution ensures the security of communications between nodes, and reduces the energy consumption of the security scheme.
