Cryptography Is Like Magic


Ensuring that information does not fall into the wrong hands requires cryptography: The communication between sender and receiver is encrypted. An example of this is the legendary Enigma cipher machine from the Second World War. Modern cryptography is also working on technologies that could resolve the tension between data use and data protection. Jörn Müller-Quade explained this by example of an application in the healthcare sector.

At the core of all cryptographic processes is an intelligent key. But how can two parties receive such a key without first having met physically? Can today's cryptographic methods be a match for the incredible computing power of future quantum computers? This presentation explored these and other "enigmatic" questions and showed that just as in magic, it is possible to convince a person of something without revealing a secret.

Prof. Dr. Jörn Müller-Quade studied computer science at the universities of Erlangen and Karlsruhe. He earned his doctorate in computer algebra at the University of Karlsruhe, now the Karlsruhe Institute of Technology (KIT). He then worked as a postdoc fellow at the University of Tokyo and headed an Emmy Noether junior research group in Karlsruhe. Since 2008, he has held the Chair of Cryptography and Security at the KIT Institute for Theoretical Computer Science. Müller-Quade has also been Director of the Research Center for Computer Science since 2010 and is a leading member of various committees, including the National Cyber Security Council.
