Efficient Rekeying Framework for Secure Multicast with Diverse-Subscription-Period Mobile Users

Efficient Rekeying Framework for Secure Multicast with Diverse-Subscription-Period Mobile Users ABSTRACT: Group key management (GKM) in mobile communication is important to enable access control for a group of users. A major issue in GKM is how to minimize the communication cost for group rekeying. To design the optimal GKM, researchers have assumed that all group […]


Discovery and Verification of Neighbor Positions in Mobile Ad Hoc Networks

Discovery and Verification of Neighbor Positions in Mobile Ad Hoc Networks ABSTRACT: A growing number of ad hoc networking protocols and location-aware services require that mobile nodes learn the position of their neighbors. However, such a process can be easily abused or disrupted by adversarial nodes. In absence of a priori trusted nodes, the discovery […]
