SURVEY ON SECURE GROUP COMMUNICATION (SGC) OVER WIRELESS NETWORK

Abstract

Wireless networks provide advantages in deployment, cost, size, and distributed intelligence over wired networks. Group communications in wireless networks has been enabling many evolving applications that require packet delivery from one or more sender(s) to multiple receivers. Due to insecure wireless communications channels, group communications are vulnerable to various kinds of attacks. Although a number of proposals have been reported to secure group communications, provisioning security in group communications in wireless networks remains a critical and challenging issue. This paper presents a survey of recent advances in security requirements and services in group communications in three types of wireless networks, and discusses challenges in designing secure group communications in these networks: wireless infrastructure networks, mobile ad hoc networks, and wireless sensor networks.
