Group key management is a fundamental building block for secure group communication systems. It is required for many applications such as teleconference, group meeting etc. Proposed system, secure group communication in public key cryptography systems is proposed for dynamic groups which are secure. In this scheme a group is established and a master key is generated using the dynamic approach chain matrix multiplication and text messages are transmitted between users of group with help of master key and also between sub groups.
