A Group Key Agreement protocol is a process to establish a cryptographic key for a group of participants over an open network. In this paper, we propose a group key agreement(CAGKA...
In order to secure communications for dynamic peer groups in mobile computing environments, key agreement protocols are required. In this paper, we propose a new key agreement pro...
The lack of fixed infrastructure, both physical and organizational, and the highly dynamic nature of ad hoc networks, presents a major challenge in providing secure, authenticate...
We present a provably secure tree based authenticated group key agreement protocol in dynamic scenario. Bilinear pairing and multi-signature are at the heart of our protocol. We p...
We present an efficient authenticated and fault-tolerant protocol (AFTD) for tree-based key agreement. Our approach is driven by the insight that when a Diffie-Hellman blinded key ...
