For deploying wireless group-oriented applications in an adversarial environment such as battlefield or disaster rescue cases, it is necessary to provide support for secure multicast communication. In this paper, pyramidal security model is proposed to safeguard a special multicast scenario of multi-security- level information broadcast in an information sharing domain of mobile ad hoc network. In order to give an efficient key management solution to the pyramidal security model, we propose an integrated tree key graph scheme. Performance comparison proves that this scheme possesses many advantages over its counterparts.
