The information security of wireless sensor networks is one of hot issues on the current research; this paper combines threshold key scheme with the management of security key sharing and group agreement and proposes dynamic key management scheme through clustering level key matrix of authentication mechanism from the cluster to node. The network is divided into different clusters, and the cluster head conducts the key authentication exchange and updates the key management with threshold key schemes, with no need of third authentication center, reduces the computing and communication costs, and promotes communication.

In recent years, wireless sensor network (WSN) applications have tended to transmit data hop by hop, from sensor nodes through cluster nodes to the base station. As a result, users must collect data from the base station. This study considers two different applications: hop by hop transmission of data from cluster nodes to the base station and the direct access to cluster nodes data by mobile users via mobile devices. Due to the hardware limitations of WSNs, some low-cost operations such as symmetric cryptographic algorithms and hash functions are used to implement a dynamic key management. The session key can be updated to prevent threats of attack from each communication. With these methods, the data gathered in wireless sensor networks can be more securely communicated. Moreover, the proposed scheme is analyzed and compared with related schemes. In addition, an NS2 simulation is developed in which the experimental results show that the designed communication protocol is workable.

A Secure Strategy for Location-Based Wireless Sensor N A cluster-based secure strategy for wireless sensor networks is proposed. The two-dimension sensing area comprises a number of clusters, each of which contains four small squares called cells. The WSNs structure is a two-layer structure. The upper layer consists of all cluster heads and the lower layer consists of all ordinary sensors managed by their cluster heads. The cluster heads establish their pairwise keys through utilizing a key pre-distribution scheme based on cluster head identifications and the ordinary sensors establish their pairwise keys through employing a dynamic key management strategy based on exclusion-based systems (EBSs). Analysis and comparison show this scheme enhances the WSNs security, decreases WSNs communication consumption, saves cluster head and sensor energy expenditure, and prolongs the lifetime of both cluster heads and ordinary sensors.etworks
