Some initiatives towards future Internet, e.g., GENI, DARPA's Active Networks, argue the need for programmability of the network components. Some other initiatives extend this with argumentation for declarative networking, where the behavior of a network component is specified using some high-level declarative language, with a software-based engine implementing the behavior based on that specification...
In modern grids, authentication is usually implemented via an X.509 PKI. Proxy certificates are employed to facilitate interaction with the grid, especially for purposes of delegation and single sign-on. However, due to the nature of proxy credentials, these can be obtained by an unauthorized third party and abused for disruptive actions or unauthorized resource consumption. We propose modifications...
The main objective of this paper is to investigate and understand how ubiquitous computing framework is applied in next generation network (NGN) and what the major challenges which require looking into are. Due to converged network and standardization of more simplified protocols, now there are many deployments that are based on ubiquitous computing framework. However, there is not very much evidence...
