Recently, much attention has been paid to research on distributed coalitions that establish trust among the members of groups of computing components in distributed environments. The Trusted Virtual Domains (TVD) that our research division is proposing is a new model of a distributed coalition for establishing multiple trusted coalitions of components on(More)
We address the fine-grained control of information flow between distributed applications to protect transactions. Confining transactions in distributed untrusted environments is crucial for Web services, distributed computing, and most e-commerce applications relying on those technologies. Applications must be protected from rogue peer applications but at(More)
An agent augmented community is a new framework that uses agent technologies for the augmentation of our community activities by integrating cyberspace, the real world, and personal contexts. We have been developing a mobile agent system that can recognize real world situations, move to remote computers, and process information through communication among(More)
A distributed coalition supports distributed mandatory access controls for resources whose security policies differ for each group of components over nodes, and provides secure information operations and exchanges with nodes that handle information over which conflicts of interest may occur. Many projects have proposed distributed coalitions using a virtual(More)
—This paper proposes an autonomic network configuration (ANC) technology, which uses autonomic technologies for the network configuration in order for electronics consumer appliances to improve usability and security. ANC provides networkable digital appliances (NDAs) with a network environment detection service and enables them to automatically configure(More)
