“…Although the harvested energy from RF signals appears to be inefficient and the WPC-based wireless communication seems to be not widely available at the current stage, practical applications for power-constrained devices of IoT have already been investigated, and more feasible applications will be implemented in the near future [6][7][8]. Until now, a lot of research efforts have also been devoted to explore the advantages of WPC in most applications of IoT since it could be easily combined with wireless terminals [9][10][11][12][13]. Specifically, typical wirelesspowered communication networks (WPCN) were investigated in [9], where introduction of a dynamic time division multiple access (TDMA) protocol was performed for a multiuser WPCN, and the best time allocation for the downlink WPC and the uplink wireless information transmission (WIT) had been analyzed.…”

“…In particular, a joint wireless power transfer (WPT) and relay selection method were proposed for WPCN in [10], where the source and relays utilize the time-switching-based RF-EH method to acquire energy from a power beacon (PB) with multiple antennas. Differently, secrecy performance discussion of EH wireless sensor networks was examined in [11], where the authors proposed an optimization method, in which a wireless-powered friendly jammer was utilized for improving the secrecy performance of the considered model. Furthermore, the authors in [12] analyzed the secrecy performance of the EH sensor system and proposed a best-relay-and-best-jammer protocol for enhancing the secrecy of a system with the source user and multiple sensor relays harvesting energy from diverse PBs.…”

In this paper, we consider the secure green-oriented multiuser scheduling for the wireless-powered Internet of Things (IoT) scenario, in which multiple source sensors communicate with a controller assisted by an intermediate sensor with the existence of a passive tapping device. Due to the limited energy, all sensors must acquire energy from external power beacons (PBs). Specifically, for the security improvement, we introduce two multiuser scheduling schemes possessing the optimal PB chosen by the relay, i.e., the best source sensor is scheduled in a random way (BSR), while the best source sensor is decided by the best PB (BSBP). Furthermore, for every scheme, we derive the analytical expressions for the secrecy outage probability (SOP) and investigate the secure energy efficiency (SEE) optimization problem with constricted transmission power in PBs. Simulation results reveal that the BSBP scheme provides better secrecy performance, and elevating the PBs quantity or reducing both the ratio of distance from PBs to source users and the total communication distance to some extent is helpful for improving SEE. In addition, the time-switching factor shows an important effect upon secrecy performance of the considered system.

“…The energy constraint requires a careful design of the communication protocols (e.g., MAC [4], routing [5] and cross-layer [6]). There are specific deployment strategies according to the characteristics and application of the network [7]. If the nodes are randomly deployed, specific techniques which detect the position of the nodes can be used [8].…”

In case of an adversary that compromises a node in a wireless sensor network (WSN) and obtains its secret material, techniques for the detection of malicious or compromised nodes have been proposed in several papers. However, the ability to recover secure communications after a compromised node has been detected has not been thoroughly investigated. Such an ability allows to evaluate the level of proper functionality, i.e., the ratio of secure links in the network, that can be recovered after a successful attach and the withdrawal of the compromised secret material. This paper defines and discusses for the first time the recoverability property and provides the formulas to compute it for the main state-of-the-art key management schemes. All the formulas are validated through extensive simulation. INDEX TERMS WSN, key management, recoverability.

An effective key management plays a crucial role in imposing a resilient security technique in Wireless Sensor Network (WSN). After reviewing the existing approaches of key management, it is confirmed that existing approachs does not offer good coverage on all potential security breaches in WSN. With WSN being essential part of Internet-of-Things (IoT), the existing approaches of key management can definitely not address such security breaches. Therefore, this paper introduces a Framework for Secure Data Aggregation (FSDA) that hybridizes the public key encryption mechanism in order to obtain a novel key management system. The proposed system does not target any specific attacks but is widely applicable for both internal and external attacks in WSN owing to its design principle. The study outcome exhibits that proposed FSDA offers highly reduced computational burden, minimal delay, less energy consumption, and higher data transmission perforance in contrast to frequency used encryption schemes in WSN.
