Secure Multicast Routing Algorithm for Wireless Mesh Networks

Abstract

Multicast is an indispensable communication technique in wireless mesh network (WMN). Many applications in WMN includingmulticast TV, audio and video conferencing, and multiplayer social gaming use multicast transmission. On the other hand, security in multicast transmissions is crucial, without which the network services are significantly disrupted. Existing secure routing protocols that address different active attacks are still vulnerable due to subtle nature of flaws in protocol design. Moreover, existing secure routing protocols assume that adversarial nodes cannot share an out-of-band communication channel which rules out the possibility of wormhole attack. In this paper, we propose SEMRAW (SEcure Multicast Routing Algorithm for Wireless mesh network) that is resistant against all known active threats including wormhole attack. SEMRAW employs digital signatures to prevent a malicious node from gaining illegitimate access to the message contents. Security of SEMRAW is evaluated using the simulation paradigm approach.

A secure and lightweight multicast communication system for Smart Grids

“…The results show that the presented proposal is an alternative to provide secure multicast without the need to any change at the network layer, and without the need of a more complex solution as generic inter-domain ALM algorithms. When compared to other generic solutions, such as [16], the GMAM reduces processing need by avoiding asymmetric key verifications. Indeed, the GMAM reduces information exchange and processing at nodes since in the GMAM do not need to build an overlay network.…”

“…To implement it some nodes of network participate in a distributed certification authority mechanism. Thus, its focus on building a distributed Certificate Authority (CA) and keys management considering protection without external adversaries [16]. However, it causes some overhead and must make changes at routing protocol.…”

“…On the work presented by [16] is proposed a secure multicast algorithm to WMN called SEMRAW. It focuses on providing a reliable tree path using a Public Key Infrastructure (PKI) to assure node authenticity but without handle the key distribution.…”

“…They use asymmetric signatures to provide authenticity and integrity to multicast routing mechanism, thus causing overhead on each WMN router once each of them must verify signatures of one-hop and two-hop neighborhood. Also, [16] provides the formal proof of its model. Several signature verification operations could be an onerous task, especially on constrained hardware.…”

High-Performance Multipath Routing Algorithm Using CPEGASIS Protocol in Wireless Sensor Cloud Environment

“…Routing algorithms classified into three types such as is multipath routing, dynamic routing and hierarchical routing. The characteristics of these routing algorithms are based on protocol design, routing speed, type of routing, network topology and bandwidth [9].…”
