Ad hoc Network Security Schema of Identity-based Encryption
Huihua Zhou · Journal of Hubei Institute for Nationalities · 2005
Wireless ad hoc networks consist of nodes with no central administration and rely on the participating nodes to share network responsibilities. Such networks are more vulnerable to security attacks than conventional wireless networks. This paper presents two efficient security schemes for these networks that use pairwise symmetric keys computed non-interactively by the nodes which reduces communication overhead.Nodes are allowed to generate their broadcast keys for different groups and propose a collisionfree method for computing such keys.The paper also introduces an authenticated broadcast scheme based on symmetric keys and a corresponding signature scheme.
