The future of quality protection belongs to electronic components and so-called RFID tags. In the future, consumers will be able to test the authenticity of a product using their mobile phones. For this, all the data has to be electronically checked.
In the framework of the “Crypta” project supported by the Federal Ministry for Transport, Innovation and Technology (BMVIT), scientists from Graz University of Technology have now developed a prototype which safeguards objects according to new standards.
Whether for checking the origin of foodstuffs or as proof of authenticity of drugs, the future will bring an increased use of electronic assistants to make sure that the quality is right. RFID (Radio Frequency Identification) technology enables objects to be identified wirelessly. “You need a reading device and an RFID tag which communicate with each other,” explains project leader Jörn-Marc Schmidt from the Institute of Applied Information Processing and Communications at Graz University of Technology. There is a difference between active and passive tags. The former are connected to a power source whereas the latter draw the required power directly from the field of the reading unit, which makes them particularly suitable, for instance, for applications in supermarkets.
For a long time the same electronic keys were used for these energy-efficient passive tags and their readers – using what experts call symmetrical methods. “In asymmetrical methods, the transmitter and receiver possess different keys. Secure digital signatures are thus made possible,” adds Jörn-Marc Schmidt. Together with the semiconductor manufacturer austriamicrosystems and RF-iT Solutions GmbH, an RFID software and services provider from Graz, the researchers have now developed a prototype which uses a standard method for passive tags for the first time. “For every tag there is a public key and a private key which remains secret,” explains Jörn-Marc Schmidt. This is a development which could be made use of everywhere where proof of authenticity is important. The research results are the gratifying outcome of the Crypta research project of the FIT-IT funding line of the BMVIT, which supports application-oriented research in information technology in particular.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
