“…The greater part of distributed/contributory-GKAs is extensions or generalizations of 2-party DH. [2][3][4][5][6] The management of keys in contributory/distributed-GKA [7][8][9][10][11] is less complex to deal with within each cluster/subgroup relative to approaches that deal with the entire group. In this direction, contemporary works 5,6,[12][13][14][15][16][17] chose cluster/subgroup-based schemes 14,16 in which the entire group is divided into clusters.…”

Group key management with privacy preserving and trust still remains a precarious and stimulating issue for securing multicast communications in an energy embarrassed large wireless ad-hoc networks (WANETs). To address this, few researchers with the adaption of blockchain technology and practical usage of a privacy-preserving smart contract as group controller made these group key agreements adaptable to WANET. However, proportionate to the increase in the size of the group, the processing load on the smart contract is also increasing, which made the capability of the smart contract could not work beyond a certain group size. Contemporary blockchain schemes suffer from various inherent shortcomings in their latency, scalability, and processing throughput. So, in this direction, we adopted blockchain sharding smart contract-centric processing for making the key agreement adaptable to large WANETs.In this technique, we divide the large network into r sharded subnetworks with G 1 , G 2 , G 3 , … , G r as smart contract instances generated by group controller G, which acts as subgroup controllers to their respective shards using blockchain sharding technique. This protocol is shown secure under the assumptions elliptic curve decision Diffie-Hellman and group-elliptic curve Diffie-Hellman. The performance analysis demonstrates that the proposed protocol is highly proficient than examined protocols for secure communication in large WANETs.

“…Key management in distributed/contributory-GKA are less difficult to deal with in each subgroup/cluster compared to the whole ad hoc network. So most recent works [18,20,21,25,26,30,31,35,39,[40][41][42] adopted subgroup/cluster based approach, in which the whole group is divided into clusters. Distinct controllers are utilized to control every cluster which minimizes the issue of imposing the work on a single point.…”

“…The majority of CK-GKAs' [18,20,21,25,26,30,31,35,39,[40][41][42] presume a hierarchical framework of the clusters or hierarchical structure, then execute a natural key agreement schemes such as, D-H [34] or the Burmester and Desmedt (BD) [3] GKA scheme, or a variety GKA schemes [3,7,16,[35][36][37][38][39] is at first implemented locally in each cluster, after that utilize these CKs in the next level with equivalent or an alternate key agreement scheme among CHs' to generate the whole group key. For further information on a comparison of the existing protocols [18,21,25,26,28,30,31,33,43] in this direction, one can refer to Table 2, summary of the key characteristics of cluster based protocols.…”

WANETS provide whenever-wherever networking amenities for communication establishment through the public wireless medium. In this environment, Secure-GKA and proficient group key management are known to be complicated tasks with respect to both computational and algorithmic points of view because of resource constraints in WANET [1]. There is an extensive range of applications for WANET which includes emergency medical services deployed in various environments which can considerably improve the quality of medical care; military applications, rescue missions, collaborative

Security supports are a significant factor in the design of security system in ad hoc networks. It is particularly important to protect the identities of individual nodes to avoid personal privacy concerns. In this paper, we propose a security system for ID-based anonymous cluster-based MANETs to protect the privacy of nodes. Moreover, we propose a threshold signature scheme without pairing computations, which diminishes the computation load on each node. To the best of our knowledge, our proposed security system is the first in which the pseudonym is combined with cluster-based mobile ad hoc networks (MANETs) without a trusted entity. According to our protocol analysis, our proposal satisfies most properties for an anonymous security system and effectively copes with dynamic environments with greater efficiency by using secret sharing schemes. Therefore, it could be usefully applied to preserve privacy in dynamic MANETs without a trusted entity, such as military battlefields, emergency areas, mobile marketplaces, and vehicular ad hoc networks (VANETs).
