This paper presents an approach for viewpoint invariant human action recognition, an area
that has received scant attention so far, relative to the overall body of work in human action …

Small low-cost sensor devices with limited resources are being used widely to build a self-
organizing wireless network for various applications, such as situation monitoring and asset …

We present GKMPAN, an efficient and scalable group rekeying protocol for secure multicast
in ad hoc networks. Our protocol exploits the property of ad hoc networks that each member …

We present the design and specification of a protocol for scalable and reliable group
rekeying together with performance evaluation results. The protocol is based upon the use …

Group-oriented applications are urgent in network communications for bandwidth
economizations. The security issues in multicast are also urgent to be addressed. And the …

Recently, many group key management approaches based on the use of logical key trees
have been proposed to address the issue of scalable group rekeying that is needed to …

Cette thèse est consacrée à l'étude des systèmes d'équations différentielles non linéaires
aux dérivées partielles. L'approche choisie est celle de l'algèbre différentielle. Étant donné …

Many multicast-based applications (eg, pay-per-view, online auction, and teleconferencing)
require a secure communication model to prevent disclosure of distributed data to …

The paper analyzes the Logical Key Hierarchy (LKH) secure multicast protocol focusing on
the reliability of the re-keying authentication process. We show that the key management in …

We focus on the problem of distributing key updates in secure dynamic group
communication. In secure groups, to reflect changing group membership, the group …
