First tap-proof communication network tested
In a few years' time, communication partners may be able to transmit their data securely over a network. A corresponding encryption technology was tested on Wednesday.

Quantum physicists in Vienna claim to have made the first ever phone call via a completely tap-proof network. With the help of a technology known as quantum cryptography, any information such as emails or video conferences can be sent securely.
Eavesdropping is not possible for physical reasons. According to the physicists, an eavesdropper cannot, in principle, obtain any information. Anyone attempting to access the transmission will be noticed by the communication partners.
This technology for encrypting data is not new, but until now it has not been possible to connect more than two points directly with each other. In Vienna, 6 points have now been linked together for the first time.
However, the transmission is still significantly slower than the internet, as quantum physicist Anton Zeilinger from the University of Vienna reported. And the data can only be sent over a maximum distance of 100 kilometers. Zeilinger does not see any fundamental problems with this; he believes that these are just technical challenges.
Siemens is already thinking about potential customers. Potential customers include the military, banks, governments and companies. According to Siemens CEO Brigitte Ederer, the system should be available to customers in three to four years.
Swiss researchers from the Universities of Geneva and Lausanne played a part in setting up the network. According to an SDA press release on Wednesday, they helped to set up several of the systems used.
