Adaptive Security for Multilevel AdHoc Networks

“Adaptive Security for Multilevel AdHoc Networks” Published in Wireless Communications and Mobile Computing 2002, pp 533-547

Authors: J. Kong, H Luo, K. Xu, D Lihui Gu, M Gerla and S. Lu

This paper proposes a security framework for multilevel adhoc wireless networks. The paper is good to read, easy to understand and not mathematical. The works deals about how to seamlessly switch from infrastructure mode to infrastructureless mode while maintaining appropriate security level. It’s interesting in the sense that I have never met with previous work that talks about how to do the transition, keeping security aspects in mind, from an infrastructure based wireless net, to an ad hoc net which does not have an access point or a central node. The transition is based on a back-up scheme with distributed certification services, in the context of an unmaned aerial verhicle (UAV). The basic idea is sensible, but storage requirements and complexity of such a mechanism, are points to investigate.

Cloud Computing’s Perfect Storm?

An Intel, Yahoo, and HP initiative will use large-scale research projects to test a new Internet-based computing infrastructure.

By John Borland

Intel, Yahoo, HP, and an international trio of research institutions announced a joint cloud-computing research initiative. The ambitious six-site project is aimed at developing an Internet-based computer infrastructure stable enough to host companies’ most critical data-processing tasks. The project also holds an unusual promise for advances in fields as diverse as climate change modeling and molecular biology.

The new array of six linked data centers, one operated by each project sponsor, will be one of the largest experiments to date focusing on cloud computing–an umbrella term for moving complex computing tasks, such as data processing and storage, into a network-connected “cloud” of external data centers, which might perform similar tasks for multiple customers.

The project’s large scope will allow researchers to test and develop security, networking, and infrastructure components on a large scale simulating an open Internet environment. But to test this infrastructure, academic researchers will also run real-world, data-intensive projects that, in their own right, could yield advances in fields as varied as data mining, context-sensitive Web search, and communication in virtual-reality environments.

Cloud Computing (Part 2)

At the fringe are the end users making the requests that initiate computations and who receive the results. Although the future of cloud computing is less than clear, a few examples of present practice suggest likely directions:

Wordstar for the Web. The kinds of productivity applications that first attracted people to personal computers 30 years ago are now appearing as software services. The Google Docs programs are an example, including a word processor, a spreadsheet, and a tool for creating PowerPoint-like presentations. Another undertaking of this kind is Buzzword, a Web-based word processor acquired by Adobe Systems in 2007. Another recent Adobe product is Photoshop Express, which has turned the well-known image-manipulation program into an online service.

Enterprise computing in the cloud.

Software for major business applications (such as customer support, sales, and marketing) has generally been run on corporate servers, but several companies now provide it as an on-demand service. The first was Salesforce.com, founded in 1999, offering a suite of online programs for customer relationship management and other business oriented tasks; the company’s slogan is “No software!”

Cloudy infrastructure. It’s all very well to outsource the chore of building and maintaining a data center, but someone must still supply that infrastructure. Amazon.com has moved into this niche of the Internet ecosystem. Amazon Web Services offers data storage priced by the gigabyte-month and computing capacity by the CPUhour. Both kinds of resources expand and contract according to need. IBM has announced plans for the “Blue Cloud” infrastructure. And Google is testing the App Engine, which provides hosting on Google server farms and a software environment centered on the Python programming language and the Bigtable distributed storage system.

The cloud OS. For most cloud-computing applications, the entire user interface resides inside a single window in a Web browser. Several initiatives aim to provide a richer user experience for Internet applications. One approach is to exploit the cloud-computing paradigm to provide all the facilities of an operating system inside a browser. The eyeOS system, for example, reproduces the familiar desktop metaphor—with icons for files, folders, and applications—all living in a browser window.

Cloud Computing (Part one)

Something is happening today in the world of computing. Data and programs are being swept up from desktop PCs and corporate server rooms and installed in “the compute cloud.” Whether it’s called cloud computing or on-demand computing, software as a service, or the Internet as platform, the common element is a shift in the geography of computation. When you create a spreadsheet with the Google Docs service, major components of the software reside on unseen computers, whereabouts unknown, possibly scattered across continents. The shift from locally installed programs to cloud computing is just getting under way in earnest. Some substantial fraction of computing activity is migrating away from the desktop and the corporate server room. The change will affect all levels of the computational ecosystem, from casual user to software developer, IT manager, even hardware manufacturer.

The new regime is not quite a return to the hub-and-spoke topology of time-sharing systems, if only because there is no hub. A client computer on the Internet can communicate with many servers at the same time, some of which may also be exchanging information among themselves. However, even if we are not returning to the architecture of time-sharing systems, the sudden stylishness of the cloud paradigm marks the reversal of a long-standing trend. Where end users and corporate IT managers once squabbled over possession of computing resources, both sides are now willing to surrender a large measure of control to third-party service providers.

What brought about this change in attitude? For the individual, total control comes at a price. Software must be installed and configured, then updated with each new release. The computational infrastructure of operating systems and low-level utilities must be maintained. Every update to the operating system sets off a cascade of subsequent revisions to other programs. Outsourcing computation to an Internet service eliminates nearly all these concerns. Cloud computing also offers end users advantages in terms of mobility and collaboration.

For software vendors who have shifted their operations into the cloud, the incentives are similar to those motivating end users. Software sold or licensed as a product to be installed on the user’s hardware must be able to cope with a baffling variety of operating environments. In contrast, software offered as an Internet-based service can be developed, tested, and run on a computing platform of the vendor’s choosing. Updates and bug fixes are deployed in minutes. (But the challenges of diversity don’t entirely disappear; the serverside software must be able to interact with a variety of clients.) Although the new model of Internet computing has neither hub nor spokes, it still has a core and a fringe.

The aim is to concentrate computation and storage in the core, where high performance machines are linked by high-bandwidth connections, and all of these resources are carefully managed.
