Abstract

With expanding communication services, clients are regularly grouped in different applications. Applications of such groups are gigantic, as are the requests for secure and reliable communication in these groups. So as to offer security for multicast applications, a group key must be changed at whatever point a member joins or leaves the group. Different proficient management methodologies have been proposed amid a decade ago that intend to diminish computational overheads. Nevertheless, they had failed to improve rekeying efficiency. So, for secure and efficient group communication in dynamic multicast groups, Efficient Group Key Management using Whale Optimization Algorithm based Elliptic Curve Cryptography (EGK-WOA-ECC) is presented. In this approach, group members are organized in hierarchical form. For each group member in the hierarchy, key server generates public key using private key of the group member. For optimal private key selection, Whale Optimization Algorithm (WOA) based Elliptic Curve Cryptography (ECC) is proposed. Using these generated public keys, a common group key is generated. Then the key server distributes the group key to a group member along with the inverse value of its private key. The group key will be updated when a member joints to a group and the updated keys are informed to the sub-group members. Besides, when a member leaves a group, the key server informs the inverse value of the leaving member to the remaining members. Thus this process will reduce the computational overhead of rekeying process. Simulation results show that the proposed approach achieves better computational overhead and communication overhead.
