In this paper we propose a minimal distribution of re-key messages strategy called "Hybrid Scalable Group Key Management approach (Hybrid SGKM) for dynamic multicast networks". The need for network applications requiring group communications will accelerate in future. The Keys possessed should be changed for every user join/leave the group so that a new user joins the group is prevented from accessing past communications and when an existing user leaves the group is prevented from accessing future communications. In our approach we try to generate and distribute keys to the group members during leave or join of members by using key graph based Boolean minimization technique in order to improve scalability. Experimental results illustrate that hybrid SGKM brings out better performance than other existing key management approaches.
