With the advent of digital technologies and wideninginternet bandwidth in recent years there has been amarked rise in new multimedia services.These servicesinclude teleconferencing, pay-per-view, interactivesimulation, software updates and real-time delivery ofstock market information.Security in groupcommunications is an important requirement when thedelivery includes confidential or copyrighted data.Proposals for multicast security solutions so far arecomplex and often require trust in intermediatecomponents or are inefficient.In this paper we present aframework using proxy key encryptions for scalablemulticast key management.The solution guaranteesperfect forward and backward secrecy.It has very lowcomplexity and overhead.We propose a simple keymanagement solution and discuss its properties.
