We present the issues related to secure multicast communication,in the presence of members who may collaborate to compromise the integrity of the system's security .We also show that the ability to compartmentalize the system compromise depends on the availabilty of trusted intermediate nodes.We also note that some variations of the recently proposed tree based schemes dont provide the required level of security and may be compromised if two appropriate members are compromised .
