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 …

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 …
