Cryptic messages boost data security

21.12.2007
The Swiss national elections in October 2007 provided the opportunity to witness quantum cryptography in ‘real-life’ action for the first time. Geneva was first in line to test the unbreakable data code developed by Swiss start-up company id Quantique, paving the way for a new era in data security.

The canton of Geneva became a world pioneer when it decided to use quantum cryptography to protect the dedicated line used for counting votes in the October national elections. The world’s first commercial quantum random number generator and quantum cryptography system was developed by the Swiss company id Quantique – a spin-off company of the University of Geneva – so the choice of Geneva to test the system in action was only appropriate.

The firm was founded in 2001 by four researchers from the University of Geneva: Nicolas Gisin, Grégoire Ribordy, Olivier Guinnard and Hugo Zbinden. According to Gisin: “Protection of the federal elections is of historical importance in the sense that, after several years of development and experimentation, this will be the first use of a 1 GHz quantum encrypter, which is transparent for the user, and an ordinary fibre-optic line to send data endowed with relevance and purpose. So this occasion marks quantum technology’s real-world début.”

All about Eve
Quantum cryptography, or quantum key distribution (QKD), enables two communicating parties to produce a shared random bit string know only to them, which can be used as a key to crypt and decrypt messages. An important and unique feature of quantum cryptography is the ability of the two communicating parties to quickly detect the presence of any third party trying to gain access to the key. This third party, the eavesdropper if you like, is commonly known as Eve among cryptographers. Quantum cryptography then is essentially all about cutting Eve out of the equation.

The use of the system developed by id Quantique makes it possible to detect Eve’s presence almost immediately and to take counter measures. The system works, however, not only when there is an eavesdropper on the line but also when data become corrupted accidentally. Which, in the case of the Swiss elections, is an equally important feature.

For Robert Hensler, the Geneva State Chancellor, the application of quantum cryptography will go a long way towards alleviating concerns over eVoting. “In this context, the value added by quantum cryptography concerns not so much protection from outside attempts to interfere as the ability to verify that the data have not been corrupted in transit between entry and storage,” he is quoted as saying.

SwissQuantum, a new standard for data security
The Swiss elections are an important milestone for id Quantique, but they are just the initial phase of a wider-ranging plan which is expected to lead to the creation of a pilot quantum communications network in Geneva similar to the nascent internet network in the United States back in the 1970s. Known as SwissQuantum, this next stage in the project aims to provide a platform for testing and validating the quantum technologies that will help to protect the communications networks of the future.

The project’s plans, however, extend beyond the Geneva region with a longer-term view of expanding the network throughout the country and beyond. This technology will appeal in particular to certain core industries of the economy which depend particularly on data security – banks, insurance companies, high-tech businesses,… In this regard, it is hoped that the SwissQuantum name will come to be seen as the best guarantee for reassuring potential clients of the soundness of this scientific innovation.

id Quantique is a partner in the European project SECOQC which began in April 2004. “The SECOQC project makes it possible for id Quantique’s engineers to interact with some of the best groups worldwide in the field of quantum cryptography,” observes Ribordy. Together, the project partners intend to lay the foundations for a long-range, high-security communication network that combines the entirely novel technology of quantum key distribution with components of classical computer science and cryptography.

Ensuring effective data security is the next challenge for global data networks. SECOCQ will provide European citizens, companies and institutions with a tool that allows them to face the threats of future interception technologies, thus creating significant advantages for the European economy.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
