With the help of multiple multicast groups, Users can subscribe to multiple groups concurrently. Existing group key management schemes mainly focusing on secure communication within single group are not applicable for multiple multicast environments because of irrelevant use of keys and larger keying overheads. This paper presents a multi-group management scheme which achieves hierarchical group access control .This scheme utilize asymmetric keys i.e. a master key and many slave keys which are wrought from master key management algorithm which is used for proficient distribution of group key.
