An Identity-Based Network Access Control Scheme for Single Authority MANETs

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 how securely extend the network. In this paper, we present INAC, an identity-based network access control scheme for MANETs. In INAC, each node in the network must have an identity-based membership token in order to take part in network activities. Membership tokens have special formats, which not only guarantee security of non-compromised nodes, but also enable that nodes obtain identity-based membership tokens based on their trustworthiness. Through simulations we verify the feasibility of our design in the single authority MANETs.
