Abstract. Wireless sensor networks (WSNs) are expected to be utilized by internet of things (IoT) applications/services in various fields in the near future. However, studies on session key establishment between two nodes in WSNs are relatively recent compared to studies on long-term key establishment. This paper proposes a security and efficiency enhanced session key establishment scheme for hierarchical sensor networks in security-critical applications. The proposed scheme employs elliptic curve Diffie-Hellman key exchange (ECDH) and RSA signature verification to efficiently perform the most important security features of mutual authentication, verification of message integrity, and session key establishment.

“…The aim of the node scheduling is to save the node energy and prolong the network lifetime with the desired QoC by shutting down the nodes in turn. Currently, most coverage control algorithms obtain the coverage information according to the location information of the nodes [4][5][6]. However, the acquisition of location information relies on external infrastructures such as the GPS and directional antennas, which greatly increases the hardware cost and energy consumption for the nodes.…”

The node deployment in mobile sensor networks (MSNs) is mostly performed in a random method. However, a large number of redundant nodes may exist due to the randomness. As a result, severe data congestion may be caused and the quality of coverage (QoC) is undermined. In order to solve this QoC problem, we propose an Energy-efficient Nonlinear Coverage Control Protocol (ENCP). This protocol utilizes the normal distribution to calculate the minimal number of sensors which is required to guarantee coverage over the monitoring area. We also balance the node energy consumption and achieve the collaborative scheduling among all the sensor nodes. Meanwhile, when a certain QoC is guaranteed, we present the calculation model for the normal distribution of the sensing ranges and the proportional relationship between different parameters in the QoC function. Finally, simulation results show that the ENCP could not only improve the network QoC and network coverage rate but also effectively control the energy exhaustion at the nodes. Therefore, the network lifetime can be effectively prolonged.

“…Moreover, for easy network management, such applications can employ clustered and hierarchical sensor networks, as shown in Figure 1 [19,20]. When employing clustered sensor networks for such applications, the communication between the gateway and the cluster head requires stronger security than the communication between the cluster head and the sensor node; this is because the cluster head collects the data sensed by sensor nodes in its cluster and transmits it to the gateway [17]. Therefore, it is appropriate to apply the session key to the communication between the gateway and the cluster head in order to increase security.…”

Security Analysis and Improvements of Session Key Establishment for Clustered Sensor Networks

WSN (wireless sensor network) is one of the main technologies in IoT (Internet of Things) applications or services. To date, several schemes have been proposed to establish a pair-wise key between two nodes in WSN, and most of them are designed to establish long-term keys used throughout the network lifetime. However, in the near future, if WSN will be used for information infrastructures in various fields such as manufacturing, distribution, or public facilities management and its life cycle can be as long as that of other common networks, it will definitely be advantageous in terms of security to encrypt messages using session keys instead of long-term keys. In this paper, we propose a session key establishment scheme for clustered sensor networks that is based on elliptic curve Diffie-Hellman (ECDH) key exchange and hash chain. The proposed scheme eliminates vulnerabilities of existing schemes for WSN and has improved security. The proposed scheme is efficient in terms of energy costs compared to related schemes.
