Adaptive trust and reputation system as a security service in group communications
Group communications has been facilitating many emerging applications which require packet delivery from one or more sender(s) to multiple receivers. Owing to the multicasting and broadcasting nature, group communications are susceptible to various kinds of attacks. Though a number of proposals …

Group Key Management in Wireless Ad-Hoc and Sensor Networks
<p>A growing number of secure group applications in both civilian and military domains is being deployed in WAHNs. A Wireless Ad-hoc Network (WARN) is a collection of autonomous nodes or terminals that communicate with each other by forming a multi-hop radio network and maintaining connectivity in …

Application of media channels to large-scale group communication
… or poor reliability, their use for real-time communications for human interaction was considered infeasible on any large scale, since audio and video data consumed vast amounts of memory and processing capacity. However, recent and forthcoming enhancements to network quality, along with …

Protocol design for scalable and reliable group rekeying
In secure group communications, group users share a symmetric key, called group key. The group key is used for encrypting data traffic among group users or restricting access to resources intended for group users only. A key server needs to change the group key after users join and leave (called …
