Multicast routing protocols are widely used as efficient communication methods for Group-oriented applications. Decentralized system is preferred to improve bandwidth economization. However, security with the key management for such protocols re-mains a significant problem. In this paper, a secure group key agreement over decentralized systems is proposed. The proposed system is based on the use of progressive approach which is a step by step improvement process. The main advantage of the authors' proposed system is the periodic Authentication of group key members.
