This paper presents a new key management protocol for group-based communications in non-hierarchical wireless sensor networks (WSNs), applied on a recently proposed IP-based multicast protocol. Confidentiality, integrity, and authentication are established, using solely symmetric-key-based operations. The protocol features a cloud-based network multicast manager (NMM), which can create, control, and authenticate groups in the WSN, but is not able to derive the actual constructed group key. Three main phases are distinguished in the protocol. First, in the registration phase, the motes register to the group by sending a request to the NMM. Second, the members of the group calculate the shared group key in the key construction phase. For this phase, two different methods are tested. In the unicast approach, the key material is sent to each member individually using unicast messages, and in the multicast approach, a combination of Lagrange interpolation and a multicast packet are used. Finally, in the multicast communication phase, these keys are used to send confidential and authenticated messages. To investigate the impact of the proposed mechanisms on the WSN, the protocol was implemented in ContikiOS and simulated using COOJA, considering different group sizes and multi-hop communication. These simulations show that the multicast approach compared to the unicast approach results in significant smaller delays, is a bit more energy efficient, and requires more or less the same amount of memory for the code.

Clustering is one of the techniques used in Wireless Sensor Networks (WSNs) to enhance the network lifetime. Network lifetime can further be improved by reducing the number of computations performed by cluster members and cluster head. This paper presents two low cost key establishment schemes for clustered sensor networks which use binomial trees for managing the clusters: BLKH (Binomial tree based Logical Key Hierarchy) scheme and BWLKH (Binomial tree based Wireless Logical Key Hierarchy) scheme. The proposed schemes avoid rebalancing of key trees during join/leave operations by replacing logical key tree by binomial key tree. In both schemes, the number of new keys generated and the number of encryptions performed during node addition/eviction are less compared to LKH++ and WLKH schemes and are quite efficient. The proposed schemes increase the performance of a sensor node by minimizing the computations at cluster members. Thus, the schemes are scalable and suitable for large scale sensor networks.

A primary important aspect of wireless network domain is known to be secured communication as the signals are emphatically available and broadcasted through the air. Quantum wireless networks are a hot topic of research in recent years that made researchers to avail new techniques in this field. Big data is one of the major aspects that support large-scale quantum network applications. As sensor nodes have resource constraints, it is more complex when using the traditional techniques of key establishment that only used for stable communication networks. Group-related applications are also one of the important aspects in wireless network for sending and receiving messages from multiple users. Unfortunately, maintenance of security for the group-oriented protocols is major issue due to the frequent changes in membership. In this paper, a hybrid GKM with re-keying procedure is proposed to obtain a secure communication for the remote system of unmanned autonomous vehicle (UAV) with mobile backbone network (MBN). Here, the group controller is selected based on the simplified hybrid energy efficient distributed (HEED) protocol and honey key encryption algorithm is used by the key management center (KMC) for generating and distribution of key for the group's controller. The secure communication is explored using the key exchange mechanism between the nodes. The joining and leaving of a node from the group are initiated by the re-keying process. The simulation results explain the improved performance of the proposed hybrid method when compared with other existing techniques in terms of privacy level, energy, memory, and time consumption.
