An Identity-Based Broadcast Encryption Scheme for Mobile Ad Hoc Networks
A Mobile Ad-hoc NETwork (MANET) is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. In this paper, the authors propose a secure identity-based ad hoc protocol for mobile devices to construct a group key for a setup of a secure communication network in an efficient way and propose a collision-free method for computing such keys. Unlike group key management protocols, they use identity-based keys that do not require certificates which simplify key management. In contrast to other interactive protocols, they only need one broadcast to setup the group key and member removal is also highly efficient.
