Winter 2011/2012

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 ...

Many small devices spread in the world: mobile phones, processors in cars, RFID tags on articles, sensor arrays. Their designers want them to communicate with each other. This is easy as long as there is no adversary. But that is real fiction. So we have to deal with the protection of communication and computation. Well, there's plenty of cryptography to do that: primitives, schemes and ...

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. The following topics will be discussed in the seminar 1. Thakur, Himanshu, ...

The topic is not yet determined.  Previous instantiations dealt with Fuzzy Coding Theory, Zero-Knowledge, PCP, Ellitpic Curve Theory, ...  In any case the topic will try to dig deeper than what you expect in a standard course or seminar. Well, this semester we decided to focus on...

The seminar discusses subjects of current interest in computer security. Some of the lectures will be given by invited guests.
