KFU's scientists developed mobile cryptography system

Exclusive research has been carried out under supervision of Prof. Arkadii Karpov of the Department of Radiophysics at the Institute of Physics.

As stated by the researcher, debuting theoretical studies on effective methods of data protection were conducted around 10 years ago and were mainly about radiowaves reflection from meteor prints. Because of the difficulties related to this method, it was decided to develop a system in human frequency band (1 GHz). Experts assume, that mobile devices will have built-in microchips generating and distributing symmetrical encryption keys based on random properties of multipath signals. This means that it will be impossible to intercept the information about private keys due to radio wave reflection from urban obstructions, such as buildings, moving objects, human and other unpredictable changes what actually forms a pair of unique keys. To determine this information one will need to predict the resulting wave effect, motion path – what is impossible.  

There are many groups studying multipath radio wave motion in urban environment, however Kazan University is the leader in phase measurement of signals.
