An Enhanced and Cost Effective Group Key Management Scheme for Multicast Network

Abstract

Key management plays a vital role in the data communications. The proposed scheme is a key management scheme that provides more efficient and secure methods for key generation and utilization. Enhanced and cost effective key management scheme achieves a secure communication between the members within the group-based network. In this scheme, the group key is generated only once which is static. Hence, it reduces the computation cost at any change in the network like member leave and member join. This papers deals with the analysis of enhanced and cost effective key management scheme with respect to communication overhead, computation cost. The analysis shows that the proposed key management scheme comprises of the most reliable methods for key generations and hence, the data communication. Enhanced and cost effective key management scheme is compared to some of the other key management techniques and proved to be the better choice in this study.

An Efficient and Variable Interval Rekeying for Dynamic Ad Hoc Multicast Group Using Key Path Reduction

“…Individual rekeying with Logical Key Hierarchy (LKH) (El-Zoghdy et al, 2011) was proposed as a solution for rekeying; it reduces the rekey communication cost considerably (Muthusamy et al, 2013). In rooted key tree for a group of N members with the degree of d, where N = 9 and d = 3, the numbers of encryptions by the key server are (Wei et al, 2007) Equation (1):…”
