Outsourcing data storage and IT workloads to a third-party cloud provider introduces some security risks and time performance degradation. Moreover, controlling access to this data becomes very difficult when the volume of the data and number of users ...

Applications are increasingly operating on large data sets. This trend creates problems for access control, which in principle restricts the actions that subjects can perform on any item in that data set. Performance issues therefore emerge, typically ...

Computing devices already permeate working and living environments; a trend which is expected to intensify in the coming years. However, the direct interaction smart devices often have with the physical world, along with the processing, storage ...

Ubiquitous devices comprising several resource-constrained sensors and actuators while having the long desired Internet connectivity, are becoming part of many solutions that seek to enhance user’s environment smartness and quality of living. ...

The need to manage embedded systems, brought forward by the wider adoption of pervasive computing, is particularly vital in the context of secure and safety-critical applications. This work presents RT-SPDM, a framework for the real-time management of ...

This paper summarises ongoing research and recent results on the development of flexible access control infrastructure for complex resource provisioning in Grid-based collaborative applications and on-demand network services provisioning. The paper ...

This paper describes the design and development of a flexible, customer-driven, security infrastructure for Gridbased Collaborative Environments. The paper proposes further development of the access control model built around a service or resource ...
