Network security plays important role in computer networks in both public and private, which are used in network transactions and communications such as businesses, government agencies and individuals. Key administration is one of the main errands in secure group communication systems. This paper proposes a cluster-based network and a secure and proficient key management scheme in multicast networks for achieving a secure communication between the group members. In this paper, process of generating self-invertible matrix for Hill Cipher algorithm has been proposed. The inverse of the matrix used for encrypting the message does not always available. If the matrix is not invertible, the encrypted message cannot be decrypted. In the self-invertible matrix generation process, the matrix used for the encryption is itself self-invertible. So, at the time of decryption, need not to find inverse of the matrix. This process decreases the computational complexity involved in finding inverse of the matrix while decryption. In this paper, we propose a secure and proficient key management scheme in multicast networks, Dynamic Architecture for Scalable and proficient Group Key Management, for achieving a secure communication between the communicating members in a cluster based network.
