QUANTUM CRYPTOGRAPHY
Dominique Unruh:
Security of communication will have to be proven by computers Dominique Unruh studied cryptography in Karlsruhe, Germany, at a University known today as The Karlsruhe Institute of Technology, before coming to Tartu ten years ago to continue his research. Unruh was one of the first in his field who started thinking and talking about quantum cryptography, a field he says must find critical solutions to the problems that quantum computers create.
W
hen he was studying, quantum cryptography was still a niche area. “When I talked to other cryptographers back then, they said they didn’t care about that. One highly-rated professor walked away when I started to talk about it. That was 15 years ago, now it has changed,” Unruh says. Cryptography is a method of protecting information and online communication through the use of encrypted codes, so that only those for whom the information is intended can read and process it. Unruh says that the systems of today will be unsafe from the moment quantum computers arrive, something he knew years ago, but is now something that a lot of scientists are hurriedly working on. “Thinking about solutions to this Estonian Centre of Excellence in ICT Research
