Risk Based Authorisation for Mobile Ad Hoc Networks

摘要

Mobile ad hoc networks (MANETs) do not share the properties of traditional wired networks, as mobile nodes are more vulnerable to security attacks. Detection of selfish, malicious or faulty nodes presents security challenges that are not encountered traditionally in wired networks. The nodes in the network need to identify, and take the necessary security measures to protect their resources against these malicious nodes. We propose a risk-based authorisation model to help build ad-hoc trust relationships, capturing the dynamic behaviour of the entities with time, and ensuring the sharing of trust information through recommendations.
