Unmanned aerial vehicle mobile ad hoc networks (UAVMANETs) formed by multi-UAV self-assembling networks have rapidly developed and been widely used in many industries in recent years. However, UAVMANETs suffer from the problems of complicated key negotiations and the difficult authentication of members’ identities during key negotiations. To address these problems, this paper simplifies the authentication process by introducing a Latin square to improve the process of signature aggregation in the Boneh–Lynn–Shacham (BLS) signature scheme and to aggregate the keys negotiated via the elliptic-curve Diffie–Hellman (ECDH) protocol into new keys. As shown through security analysis and simulations, this scheme improves the efficiency of UAVMANET authentication and key negotiation while satisfying security requirements.

“…The Quorum and Latin square Channel Hopping (QLCH) protocol is proposed in [15], where the time slots for secondary users are divided into default and switching slots. In [16], an efficient channel hopping protocol called randomized QLCH protocol (RQL) is proposed. Nodes running RQL may change their original channel hopping sequences dynamically according to their intended receivers.…”

In cognitive radio technology, the overall efficiency of communications systems can be improved without allocating additional bands by allowing a secondary system to utilize the licensed band when the primary system, which has the right to use the band, does not use it. In this paper, we propose a fast and reliable common channel initialization protocol without any exchange of initialization messages between the cluster head and the member nodes in cognitive ad-hoc networks. In the proposed method, the cluster and member nodes perform channel-based spectrum sensing. After sensing, the cluster head transmits a system activation signal through its available channels with a predetermined angle difference pattern. To detect the cluster head's transmission channels and to join the cluster, each member node implements fast Fourier transform (FFT) and computes autocorrelation for the angle difference sequence of the received signal patterns. This is compared to the predetermined reference angle difference pattern. The join-request and channel-decision procedures are presented in this paper. Performance evaluation of the proposed method is presented in the simulation results. This version includes a concrete analysis and supporting implementation results on initial rendezvous protocol using multicarrier operation.

“…Recently, a number of sequence‐based CH rendezvous approaches (cf. [8–40]) have been developed to achieve bounded MTTR for any pair of rendezvous nodes. However, the rendezvous difficulty problem for the discovery of a common channel between two rendezvous nodes still remains because they cannot exchange any information regarding the asymmetric perceptions of channel availability.…”
