Trust me, I’m a machine


An EU computer science project hopes to make the uncertainty attached to the pervasive computing future a lot more secure through establishing trust.

Using the cost-benefit function at the heart of risk analysis, the IST programme-funded SECURE project developed software to integrate the very subjective, human concept of trust into computers, PDAs, mobile ’phones and other network devices.

Pervasive computing is a steadily emerging reality. Mobile phones and PDAs are becoming powerful computers in their own right, cars now routinely include telematics, which allows them to know where they are, for example. Now vending machines that accept payment from your mobile phone or PDA are in deployment. All of these devices will periodically connect to the network to perform transactions, whether it’s information, services or purchases.

But as the network spreads and the devices that can access it multipy it is very difficult to maintain security. How do you know the person, or the machine, will not steal your personal information or that they will supply the goods, services or information you purchase?

"We’ve developed software that allows judgement based on establishing a value of trust and balancing that against the risk of abuse. We’ve mostly work on developing a system to stop spam, so the software would ask establish if the email is trustworthy. We also looked at using the service for an e-purse, an electronic purse for small transactions," says Vinny Cahill, coordinator of the SECURE project at Trinity College, Dublin.

The concept works like this: your PDA or mobile phone receives a query about your current location. First it establishes the identity of the request. Then your PDA or e-purse asks its trust calculator how trustworthy you are. The calculator bases this on previous experiences. If this is the first time, it will base it on your reputation or rating with others or, in the SECURE system, it can even delegate authority to another party.

Meanwhile the risk evaluator is calculating the cost of the transaction if your trust is abused. If the trust is greater than the risk, you PDA reveals your location. If it is unsure, it asks the user. This could be very helpful if you’re near a store that’s offering a discount on something you need.

The group says their software scheme can even work offline, the based on experience in similar situations.

SECURE developed their software in Java, which means it can work on almost any device.The project finished in December 2004, when it completed development of a software framework that can incoporated to various applications.

"Trust is emerging as a viable method for creating and using ad hoc networks and we’d like to take it further, but it will be another two or three years before it could be deployed in a commercial application," says Prof. Cahill.

Im Focus: Space observation with radar to secure Germany's space infrastructure

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
