The Multimedia Internet KEYing (MIKEY) specification describes a key management scheme for real-time applications. In this document, we note that the currently defined MIKEY modes are insufficient to address deployment scenarios built around a centralized key management service. Interest in such deployments is increasing. Therefore, a set of new MIKEY modes that work well in such scenarios are ...

Real time communication can drastically improve the fault/failure of distributed transformers and feeders . The root cause behind failures is lack of current operating information and hence leads to lack of precautions and preventive measures. The proposed scheme demands real time communication between centralized control station and distributed located substations. Due to availability of curre...

Multimedia content delivery to capable smart phones with high-speed next-generation Internet connectivity is becoming commonplace. However, the openness of delivery demands adaptive and robust management of intellectual property rights. The purpose of this article is to describe a framework to address the central issues in content delivery: a scalable peer-to-peer-based content delivery model. ...

Because of different constraints such as the customers unceasing requirements, the large distribution of systems, the permanent modifications of the management environments themselves, etc., the environments devoted to the management of the inter-domain communications security must be generally dynamic and policy based. In this work, we will present a management environment, that is mainly base...

An important component in the fields of ecology and conservation biology is understanding the environmental conditions and geographic areas that are suitable for a given species to inhabit. A common tool in determining such areas is species distribution modeling which uses computer algorithms to determine the spatial distribution of organisms. Most commonly the correlative relationships between...

We apply SecPAL, a logic-based policy language for decentralized authorization and trust management, to our case study of automated software distribution for airplanes. In contrast to established policy frameworks for authorization like XACML, SecPAL offers constructs to express trust relationships and delegation explicitly and to form chains of trusts. We use these constructs in our case study...

Knowledge transfer has been an important issue for organizational knowledge management programs. This article reviews the plethora of user-generated video activity and the issues it creates for knowledge management activities. Video’s media richness combined with its ability to convey rich narratives can facilitate sensemaking and learning. However, structure and culture are important factors t...

the purpose of this study is to investigate the effect of information technology and knowledge management on the supply chain agility in alborz darou and alborz distribution company. the statistical population of this study includes employees of alborz darou and alborz distribution company. the population consists of 426 members. a sample of 205 employees was selected through random stratified ...

Qualitative data is now commonly collected, stored, collated and analysed in digital formats, introducing new challenges for computer support. The burgeoning scale and complexity of digital data has meant that qualitative analysis tools are becoming increasingly popular options for managing and collaborating over social scientific data. One particularly important development is that distributed...
