%X The communication sector is flourishing in many ways, leading to a growing number of users and system attached to the Internet which drives the need for efficient multicast communication architecture over the Internet. Multicasting has been at the center of Internet in the area of Internet activities and has already contributed to some major successes. As multicast communication runs closer towards widespread deployment, security issues have become a central concern and are increasingly important. The features that make multicast particularly significant also make security in multicast difficult. This paper looks at the impressive changes that have been needed in multicast key management architecture and also attempts to avoid the unauthorized duplication of data. It uses tree based subgroups approach which helps to minimize re-keying overhead and also to protect unconstitutional distribution of multicast data without intended users concern.
