Cryptography (4+2 SWS, 8 ECTS credits. Optionally, 3+2 SWS, 6 ECTS credits. )

Prof. Joachim von zur Gathen
Tutorial: Raoul Blankertz, Daniel Loebenberger
Cryptography deals with methods for secure data transfer. In earlier times this was the domain of military and intelligence agencies, but today modern cryptography has grown into a key technology, enabling e-commerce and secure internet communications. Its many applications range from credit and debit cards, mobile phones, tv decoders, and electronic money to unforgeable electronic signatures ...

Topics in theoretical cryptography: Pairing-based cryptography
Advanced cryptography: Pairing-based cryptography
(4+2 SWS, 8 ECTS credits. Optionally, 3+2 SWS, 6 ECTS credits. )

Michael Nüsken
Tutorial: Daniel Loebenberger
Elliptic curve cryptography is important for a long time now. But only recently pairings start to play an important role in the design of cryptosystems. They allow to build much more efficient cryptosystems than earlier construction. And these systems usually come with security reductions to mathematical problems that seem to be reasonably difficult. However, they also require the use of very ...

Conference: Monday, 4 February 2013, 1300, B-IT Marschallsaal

Seminar Mobile Security (2 SWS, 4 ECTS credits. )

Prof. Joachim von zur Gathen, Konstantin Ziegler
The increasing use of mobile devices (in particular smart phones) over the last decade requires additional security considerations. Due to the lack of physical security, the air interface is prone to attacks. In this seminar we will look at security issues in mobile networks and we will see attacks and countermeasures. You find the slides of the organizational meeting here as a ...
  • Thursday, 1000-1200, b-it 1.25.
First meeting: Thursday, 25 October 2012.

Seminar Advanced Topics in Crytography (2 SWS, 4 ECTS credits. )

Michael Nüsken
The topic is not yet determined.  Previous instantiations dealt with fuzzy coding theory, Zero-Knowledge, PCP, ellitpic curve theory, analytical number theory, ...  In any case the topic will try to dig deeper than what you expect in a standard course or seminar. Options This semester's topic is... Universal composability framework (Canetti 2005)
  • Monday, 1700, B-IT 1.25
First meeting: Monday, 12 November 2012, 1700, B-IT 2.1
