Suppose that an organization O wants to do the following: to reveal only part of its network map; to filter unwanted traffic passing through its network; and to route, to the right destination, legitimate traffic intended for hidden parts of its network. This would enable O to perform traffic filtering and routing with improved resistance against network mapping attacks. This paper proposes a provably-secure hierarchical identity-based group signature scheme which meets the above requirements, and is scalable to large, distributed, and hierarchically-structured networks.
