According to a report published in The New York Times, there is a growing belief among engineers and security experts in USA that the only way to fix Internet security is to recreate the Internet from scratch. What a new Internet might look like is being discussed, but one possible solution would create a system in which users would relinquish their anonymity and certain freedoms in return for safety.

As more secure networks are created, the current Internet will continue to become an increasingly dangerous area that legitimate users will want to avoid. “Unless we’re willing to rethink today’s Internet,” says Nick McKeown, a Stanford University engineer working on building a new Internet, “we’re just waiting for a series of public catastrophes.” Last year, a malicious software program believed to have been released by a criminal organization in Eastern Europe infected more than 12 million computers after bypassing the world’s best cyberdefenses. Internet security continues to deteriorate globally and even the most heavily protected military networks have proved vulnerable. “In many respects, we are probably worse off than we were 20 years ago, because all of the money has been devoted to patching the current problem rather than investing in the redesign of our infrastructure,” says Purdue University professor Eugene Spafford, the executive director of Purdue’s Center for Education and Research in Information Assurance and Security. The Stanford University Clean Slate project is developing a system that will allow a more advanced network to be established underneath the current Internet. The new network will be running on eight campus networks around the United States by the end of summer 2009.

Two decades ago a 23-year-old Cornell University graduate student brought the Internet to its knees with a simple software program that skipped from computer to computer at blinding speed, thoroughly clogging the then-tiny network in the space of a few hours.

The program was intended to be a bit of cybernetic fungus that would unobtrusively wander the net. However, a programming error turned it into a much worse phenomenon, and since then things have gotten even more worse.

Bad enough that there is a growing belief among engineers and security experts that Internet security and privacy have become so maddeningly elusive that the only way to fix the problem is to start all over again.

As a new and more secure network becomes widely adopted, the current Internet might end up as the bad neighborhood of cyberspace. You would enter at your own risk and keep an eye over your shoulder while you were there.

Last year, a malicious software program thought to have been unleashed by a criminal gang in Eastern Europe suddenly appeared after easily sidestepping the world’s best cyberdefenses. Known as Conficker, it quickly infected more than 12 million computers, ravaging everything from the computer system at a surgical ward in England to the computer networks of the French military.

Conficker remains a ticking time bomb. Conficker could be used as the world’s most powerful spam engine, perhaps to distribute software programs to trick computer users into purchasing fake antivirus protection. Or much worse. It might also be used to shut off entire sections of the Internet. But whatever happens, Conficker has demonstrated that the Internet remains highly vulnerable to a concerted attack.

“If you’re looking for a digital Pearl Harbor, we now have the Japanese ships streaming toward us on the horizon,” Rick Wesson, the chief executive of Support Intelligence, a computer consulting firm, said recently.

The Internet’s original designers never foresaw that the academic and military research network they created would one day bear the burden of carrying all the world’s communications and commerce. There was no one central control point and its designers wanted to make it possible for every network to exchange data with every other network. Little attention was given to security. Since then, there have been immense efforts to bolt on security, to little effect.

In fact, many computer security researchers view the nearly two decades of efforts to patch the existing network as a Maginot Line approach to defense, a reference to France’s series of fortifications that proved ineffective during World War II. The shortcoming in focusing on such sturdy digital walls is that once they are evaded, the attacker has access to all the protected data behind them. “Hard on the outside, with a soft chewy center,” is the way many veteran computer security researchers think of such strategies.

THE University of California, Los Angeles (generally known as UCLA) is one of the best public research universities in USA and the fact that I receives an annual endowment of over $ 2.3 billion shows the amount of research that is happening around the place. As the name would suggest, the university is located in Los Angeles, California. It was founded in 1919 and the name was changed in 1927 to the University of California at Los Angeles. UCLA comprises the College of Letters and Science (the primary undergraduate college) as well as undergraduate colleges Arts and Architecture, Herb Alpert School of Music, Henry Samueli School of Engineering and Applied Scienceý, Nursing, and Theater, Film, and Television, seven professional schools, and five professional Health Science schools. Since 2001, UCLA has enrolled over 33,000 total students annually, and that number is steadily rising.

UCLA’s undergraduate program is ranked 25th among “America’s Best Colleges 2009: National Universities” by U.S. News & World Report, third among public universities in the United States. The Academic Ranking of World Universities ranked UCLA 13th internationally. UCLA is a Public Ivy, and one of the 25 New Ivies, a list of universities ranked by Kaplan. UCLA also ranks among the top 10 schools in USA with the most faculty awards.

UCLA has more applicants than any other university in the United States. Out of 55,401 undergraduate applicants for Fall 2008, only 12,755 (22.7%) were admitted. Students come to UCLA from all 50 states of USA and more than 100 countries.

When UCLA opened its new campus in 1929, it had four buildings. Today, the campus includes 163 buildings across 419 acres (1.7 km²) in the western part of Los Angeles. The Romanesque Revival style of these first four structures remained the predominant building style on campus until the 1950s, when architect Welton Becket was hired to supervise the expansion of the campus over the next two decades. In order to accommodate UCLA’s rapidly growing student population, multiple construction and renovation projects are in progress, including expansions of the life sciences and engineering research complexes. This continuous construction gives UCLA the interesting on-campus nickname of Under Construction Like Always.

The campus includes sculpture gardens, fountains, museums, and a mix of architectural styles. The campus is informally divided into North Campus and South Campus, which are both on the eastern half of the university’s land. North Campus is the original campus core; its buildings are more old-fashioned in appearance and clad in imported Italian brick. North Campus is home to the arts, humanities, social sciences, law, and business programs and is centered around oak tree-lined Dickson Court. South Campus is home to the physical sciences, life sciences, engineering, psychology, mathematical sciences, all health-related fields, and the UCLA Medical Center.

The tallest building on campus is named after Ralph Bunche, an African-American alumnus, who received the 1950 Nobel Peace Prize for negotiating an armistice agreement between the Jews and Arabs in Palestine. A bust of him, on the entrance to Bunche Hall, overlooks the Franklin D. Murphy Sculpture Garden. He was the first individual of non-European background and the first UCLA alumnus to be honoured with the Prize.

With a location near Hollywood and a world-famous film and television school, the UCLA campus has attracted filming for decades. Much of the 1985 film Gotcha! was shot at UCLA, as well as John Singleton’s Higher Learning (1995). Legally Blonde, “Old School”, “The Nutty Professor”, Erin Brockovich, and American Pie 2 all were mainly shot at the university campus or locale. In January 2009, the Bollywood movie My Name is Khan was shot at UCLA.

UCLA was ranked 12th in Newsweek’s annual ranking of the Top 100 Global universities. In 2007, UCLA was ranked 13th in the world (11th in North America) by Top 500 World Universities, an annual list published by the Institute of Higher Education at Shanghai Jiao Tong University, China. UCLA was ranked 18th in the country and 41st in the world by The Times Higher Education Supplement’s list of the top 200 universities in the world.

UCLA is ranked 25th among “America’s Best Colleges 2009: National Universities” by U.S. News and World Report, third best public university in the United States. In the August 2128, 2006 issue of Newsweek (also released as the 2007 issue of the Kaplan Guide to Colleges), UCLA was listed as one of “25 New Ivies”. The Washington Monthly ranks UCLA 2nd nationally with criteria based on research, community service, and social mobility. UCLA’s School of Law, Anderson School of Management, School of Public Affairs, and School of Medicine consistently rank among the top ten to twenty in the United States.

UCLA’s library system has over eight million books and 70,000 serials spread over twelve libraries and eleven other archives, reading rooms, and research centers.

Six professors (two of whom are current faculty) and four alumni have been awarded the Nobel Prize for achievements in science and peace. 90 professors are members of the American Academy of Arts and Sciences, 52 have been awarded Guggenheim Fellowships, and nine are MacArthur Foundation Fellows. In 2006,54 faculty members were listed as “Highly Cited” by the Institute for Scientific Information.

[StarTech] TechNews – Revolutionary microchip on cards

February 13, 2009 · Leave a Comment

http://www.thedailystar.net/pf_story.php?nid=75654

Researchers at Rice University (USA) and Nanyang Technological University (Singapore) have developed a microchip that is cleaner and greener and yet 7 times faster than the chips in use today!

In the first real-world test of a revolutionary type of computing that thrives on random errors, scientists have created a microchip that uses 30 times less electricity while running seven times faster than today’s best technology. The U.S.- Singapore team developing the technology, dubbed PCMOS revealed the results recently at the International Solid-State Circuits Conference (ISSCC), the world’s premier forum for engineers working at the cutting edge of integrated-circuit design.

Conceived by Rice University Professor Krishna Palem, PCMOS is built on the “complementary metal-oxide semiconductor” technology, or CMOS, that chipmakers already use. That means chipmakers won’t have to buy new equipment to support PCMOS, or “probabilistic” CMOS. Although PCMOS runs on standard silicon, it breaks with computing’s past by abandoning the set of mathematical rules — called Boolean logic — that have thus far been used in all digital computers. PCMOS instead uses probabilistic logic, a new form of logic developed by Palem and his doctoral student, Lakshmi Chakrapani.

“PCMOS is fundamentally different,” Palem said. “We lower the voltage dramatically and deal with the resulting computational errors by embracing the errors and uncertainties through probabilistic logic.”

PCMOS was jointly validated by Rice and Nanyang Technological University (NTU) in Singapore via a joint institute that Palem founded in 2007, the Institute for Sustainable Nanoelectronics (ISNE). Directed by Palem, ISNE is based at NTU, where the first prototype PCMOS chips were manufactured last year in collaboration with Professor Yeo Kiat Seng and his team.

The prototypes were application-specific integrated circuits, or ASICs, that were designed solely for encryption. Unlike the general-purpose microprocessors that power PCs and laptops, ASICs are designed for a specific purpose, and they are “embedded” by the millions each year in a growing constellation of products like automobiles, cell phones, MRI scanners and electronic toys.

The Rice-NTU team plans to follow its proof-of-concept work on encryption with proof-of-concept tests on microchips for cell phones, graphics cards and medical implants.

Palem said PCMOS is ideally suited for encryption, a process that relies on generating random numbers. It’s equally well-suited for graphics, but for different reasons. In a streaming video application on a cell phone, for example, it is unnecessary to conduct precise calculations. The small screen, combined with the human brain’s ability to process less-than-perfect pictures, results in a case where the picture looks just as good with a calculation that’s only approximately correct.

“The key is to consider the value that the computed information has for the user,” said Palem, who directs Rice’s Value of Information-based Sustainable Embedded Nanocomputing Center, or VISEN. “Our goal is green computing. We’re looking for applications where PCMOS can deliver as well as or better than existing technology but with a fraction of the energy.”

If PCMOS can slash energy use for embedded ASICs in key devices, the implications are enormous. For consumers, it could mean the difference between charging a cell phone every few weeks instead of every few days. Globally, that would help reduce the information technology industry’s carbon footprint.

University of Southampton

February 1, 2009 · Leave a Comment

http://thedailystar.net/campus/2009/02/01/abroad.htm

SITUATED in the south coast of England in the city of Southampton, the University of Southampton has today grown to be one of the finest institutions for higher study in UK and Europe, specially known for its Enginnering schools. Established in 1862 as the Hartley Institution, it was upgraded to the status of a university college in 1902, and by a Royal Charter in 1952, was turned into a public research-intensive university. Today, with world class research and hundreds of students studying for their PhD, Masters and Undergraduate Degrees, the university truly lives up to its motto of Strenuis Ardua Cedunt (The Heights Yield to Endeavour).

The University of Southampton is a member of the Russell Group and of the Worldwide Universities Network. It has constantly been ranked as one of the best research universities in UK by its RAE (Research Assessment Exercise) assessments, and according to The Times Higher Education Supplement, the University has the second largest research income among British universities for the physical sciences and mathematics, and the third largest research income for engineering and technology. The University places great emphasis on inter-disciplinary cooperation and on collaboration with industry.

Before 1952, the University of London gave the degrees at Southampton and in a Royal Charter that year, the Queen granted the university of Southampton a right to award degrees in its own right. This conferred full university status and made Southampton independent of the University of London. It grew rapidly and gained a reputation for a strong academic approach.

The University’s main buildings are situated on a large site on the campus in Highfield, but the University has other campuses elsewhere around the city: at Boldrewood (biomedical sciences), Southampton General Hospital and on the waterfront at the National Oceanography Centre.

It also has a campus in the nearby city of Winchester which is the home of the University’s School of Art, known as the Winchester School of Art. The Avenue Campus houses most of the Humanities subjects taught at the University, including History, English, Film, Philosophy and Modern Languages. The Centre for Language Study is based at Avenue Campus. Archaeology is also located there in a series of purpose-designed buildings (the most modern archaeology facilities of any British university). Music is taught on the Highfield Campus, near the Turner Sims Concert Hall.

The University of Southampton and the MIT recently announced the launch of a long-term research collaboration, the Web Science Research Initiative (WSRI), that aims to produce the fundamental scientific advances necessary to guide the future design and use of the World Wide Web.

The School of Electronics and Computer Science, generally abbreviated “ECS”, is regarded by the IET (Institution of Engineering and Technology) as having the “biggest and strongest academic unit in the country in Electrical and Electronic Engineering” and has been at the forefront of the Open Access movement. Its research has achieved the top 5* rating in the last two Research Assessment Exercises, and in 2003 it was awarded the prestigious ‘best 5*’ rating by the Higher Education Funding Council for England (HEFCE).

Chaired by Sir Tim Berners-Lee, the school is regarded as one of the best in the UK for both computer science and electronics, scoring 5th and 1st for the subjects respectively in the Guardian Unlimited University Guide 2008 and 5th and 2nd respectively by both the Times Online Good University Guide and the Good University Guide.

ECS was the first academic institution in the world to adopt a self-archiving mandate (2001) and since then much of its published research has been freely available on the Web. It created the first and most widely used archiving software (EPrints) which is used worldwide by 213 known archives and continues to be evolved and supported from the School.

The University of Southampton did particularly well (25th) on the G-factor metric, which uses Google links to measure the influence of universities’ research. Southampton came third among British universities, behind Cambridge and Oxford.

The University of Southampton Students’ Union (SUSU), is sited in three buildings opposite the main Library.The multiple award winning student radio station, Surge, broadcasts from new studios in the main Union building. The award winning website SUSU.org was created and run by students at the university. The student newspaper, originally Wessex News, is now published once every three weeks as Wessex Scene following a name change in 1996.

The University provides accommodation for all first year students who require it. Places in halls are also available for international and postgraduate students. Accommodation may be catered or self catered.

Notable academics to work at the university include Sir Tim Berners-Lee, inventor of the World Wide Web, Erich Zepler who made leading contributions to radio receiver development, Professor David N. Payne who invented EDFA for use in fibre optics cables.
