Executive Summary

A mobile Ad-Hoc network is a collection of wireless mobile nodes, dynamically forming a temporary network without the use of any existing network infrastructure or centralized Administration. Providing security support for mobile Ad-Hoc networks is hard to achieve due to the vulnerability of the links, the limited physical protection of the nodes, and also this fact that wireless networks are susceptible to attacks ranging from passive eavesdropping to active interfering and also mobile users demand "Anywhere, Anytime" services. This paper presents a new Composite Key Management scheme in Ad-Hoc networks. Its approach works to decrease complexity of PKI in traditional public-key certificated-based systems and securely improves key-revocation and key-renewal approaches in ID-based systems.
