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.
