This paper proposes a novel scheme of group key management based on Jacobian Elliptic Chebyshev Rational Map, named Jacobian Group Key Management(JGKM). The scheme is more efficient than other group key managements since fewer re-keying messages are sent when group membership changes. Besides, it provides both forward and backward secrecy. Therefore, this proposal is helpful to deploy secure mu...
This paper describes the design, implementation, and evaluation of Mykil, which is a new key distribution protocol for secure group multicast. Mykil has been designed to be scalable to large group sizes. It is based on a combination of group-based hierarchy and key-based hierarchy systems for group key management. Important advantages of Mykil include a fast rekeying operation for large group s...
The third important aspect of security is encryption to transfer messages among the users in a secure manner. Group key management discussed in the earlier chapter is applicable for transferring messages securely to the members in a group. Apart from transferring messages to the members in a group, messages can be transferred securely to an individual user. Encryption plays a major role in such...
Multicast routing protocols are widely used as efficient communication methods for Group-oriented applications. Decentralized system is preferred to improve bandwidth economization. However, security with the key management for such protocols re-mains a significant problem. In this paper, a secure group key agreement over decentralized systems is proposed. The proposed system is based on the us...
We present a hybrid group key management protocol that incorporates both a centralized and a contributory scheme for key management, and a tree-based Elliptic Curve Diffie-Hellman technique for group key updates. It combines the advantage of the centralized approach’s efficiency and the contributory scheme’s fault tolerance. In addition, our rekeying algorithm updates the group key in the prese...
Emerging applications require secure group communications around hierarchical architecture protocols, like military or public emergency applications. However, conceiving such secure hierarchical protocols is not straightforward. Thus, their verification become a primordial issue in order to avoid the possible security attacks and vulnerabilities. Several attempts have been done to deal with for...
Multicast is an internetwork service that provides efficient delivery of data from a source to multiple receivers. It reduces the bandwidth requirements of the network and the computational overhead of the host devices. This makes multicast an ideal technology for communication among a large group of participants. Secure group communications involves many service types include teleconferencing,...
