In any systems or environments within a ubiquitous computing context that promotes the concept of users interaction or inter-organization communication, more specifically data sharing and takes users within such context as relevant contextual information, there is the potential for interactions between systems to occur that may affect the security of the overall system. We present a scenario that...
In this paper, we propose a novel intrusion detection (ID) method, distributed court system (DCS), that is applied on OLSR (optimized link state routing) protocol in mobile ad hoc networks (MANETs), to solve link spoofing in topology control (TC) messages. This system performs similar functions as a court in real-life. Network is organized into one-hop clusters, in which each node performs local monitoring,...
Quantum communication networks need to securely transmit a quantum frame from source to destination. In the wireless communication network, source and destination have two types of connection: direct or indirect communication. In the direct connected mode, the transmission security can be achieved by using a quantum key distribution. In the indirect connected mode, it is a difficult problem to deal...
In this paper, we propose a location-release signature scheme based on bilinear pairings for vehicular ad hoc networks (VANETs). Location-release signature is a capsule signature signed by a source location server that becomes valid after the signature arrives at a specific destination location, where a location server publishes some trapdoor information associated with such a destination location...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
