ID-NAC: Identity-based network access control for MANETs
Narges Aghakazem Jourabbaf, Ali Movaghar · 2008
Security in mobile ad hoc networks (MANETs) is an active research topic. Bulks of prior work focused on key management and secure routing without addressing an important pre-requisite: network access control, the problem of admission and revocation of ad hoc nodes. In this paper, we present ID-NAC, identity-based network access control for MANETs. In ID-NAC each node in the network maintains a profile table, which contains information about the behavior of the nodes in the MANET. It is used to assign a quantitative value for the trustworthiness of a node. Since, there is no observation about the behaviors of prospective members at first; they are admitted to the network tentatively. Then, their behaviors are monitored in the network and if they behave well, they can obtain an identity-based membership tokens based on their trustworthiness. In addition, using profile tables provide protection against wrongful revocation of membership tokens through malicious accusations. The feasibility of ID-NAC was verified by simulation.
