Multicast communication is becoming the basis for a growing number of applications. It is therefore critical to provide sound security mechanisms for multicast communication. Yet, existing security protocols for multicast offer only partial solutions. We first present a taxonomy of multicast scenarios on the Internet and point out relevant security concerns. Next we address two major security p...

Key distribution is an important problem for secure group communications. Multicast is an efficient means of distributing data in terms of resources usage. All the designated receivers or members in a multicast group share a session key. Session keys shall change dynamically to ensure both forward secrecy and backward secrecy of multicast sessions. The communication and storage complexity of mu...

Many emerging applications in mobile adhoc networks involve group-oriented communication. Multicast is an efficient way of supporting group oriented applications, mainly in mobile environment with limited bandwidth and limited power. For using such applications in an adversarial environment as military, it is necessary to provide secure multicast communication. Key management is the fundamental...

With the increasing proliferation of computer networks and distributed systems, there is a growing number of applications using multicast communication. This paper presents the Vartalaap system developed at IIT, Bombay. Vartalaap is an hierarchical distributed system for multicast communication over a network, implemented in a hardware-independent fashion. The multicast is achieved without reso...

In this paper, we consider multicast device-to-device (D2D) direct communication underlaying cellular network where D2D multicast link reuses uplink frequency resources of cellular communication. We assume that a D2D multicast transmitter is equipped with multiple transmit antennas. Hence, well-known multiple antenna transmission schemes can be used in D2D multicast transmitter to reduce the in...

For large-scale multimedia distributions, multicast is the preferred method of communication. ASM (Any Source Multicast) and SSM (SourceSpecific Multicast) are the two types of multicast used. ASM is designed for either many-to-many or one-to-many communication. SSM is derived from ASM. SSM is used when only one session member is allowed to send data. An example use of SSM could be an IPTV broa...

A key issue in designing software multicast algorithms is to consider the trade-off between performance and portability. Portable software multicast algorithms which base on generic communication models cannot capture some architecture-specific features. Without considering the underlying network architecture, these multicast algorithms may not achieve the truly optimal performance when impleme...

Many emerging commercial and military applications require secure multicast communication in adhoc environments. Secure multicast communication in mobile adhoc networks is challenging due to its inherent characteristics of infrastructure-less architecture with lack of central authority, high packet loss rates and limited resources such as bandwidth, time and power. Hence key management is the f...

Multicast communication is one of the most important collective communication operations and is highly demanded in telecommunication environments and scalable parallel and distributed computing systems. In this paper, we consider the issue of supporting multicast in the widely used three-stage Clos network or v(m;n; r) network. We improve a recently proposed analytical model [7] for the blockin...

I. INTRODUCTION Emerging popular applications like IPTV and MMORGs urge the need for multicast. However, there is no global multicast deployment available today. At the same time many traditional and mobile systems would largely benefit from ease and efficiency of a network group service. A uniformly available multicast service will offer the chance to replace proprietary workarounds deployed i...
