| Colloquia The mathematical Foundations of Information theory from Claude Shannon Joachim Rosenthal Mathematics, Universität Zürich |
In this overview talk we will explain how the first two challenges concerning coding theory have resulted in practical solutions which are very close to optimal. Then we explain why the gap between the practical implementation of cryptographic protocols with the theoretical result of Shannon is largest.

Biography: Joachim Rosenthal received a Diploma in mathematics from the University of Basel in 1986 and his Ph.D. in mathematics from Arizona State University in 1990. From 1990 to 2006, he was with the University of Notre Dame, USA, where he held the Endowed Chair of applied mathematics and a Concurrent Professor of electrical engineering. Since 2004, he has been a Professor of applied mathematics with the University of Zurich. He is a fellow of IEEE, a fellow of SIAM and an Honorary Professor at Universidad del Norte, Colombia. He currently serves as President of the Swiss Mathematical Society.

| Colloquia The Standardization of Post-quantum Cryptography Joachim Rosenthal Mathematics, Universität Zürich |
Until a few years ago most public key systems were based on the hardness of factoring integers or on the hardness of the discrete logarithm problem in an elliptic curve. With the realization that a quantum computer would make many practically used public key cryptographic systems obsolete it became an important research topic to design public key systems which are expected to be secure even if a powerful quantum computer would exist.
This new area of research is called post-quantum cryptography and there has been in the last couple of years a lot of effort to come up with new standards to be used in everyday applications. The National Institute of Standards and Technology (NIST) currently conducts a standardization process.
The main part of the lecture will overview this recent development and will explain the underlying mathematical problems.
