Cybersecurity (2022)

Description:
Typical attacks on critical infrastructures: How hackers can abuse the Internet of Things, and how attacks can be prevented and detected. 

In the course, we will discuss public-key cryptosystems, which are widely used for secure data transmission. Public key cryptography aims at solving the problem of how two parties can communicate securely when they have not agreed on some secret common key, which is often the case in for example communication through the internet. It includes both public-key encryption, which guarantees the secrecy of a message, and digital signatures, which provide authentication and integrity. We will introduce some of the more classical, but still widely used, public-key cryptosystems, such RSA and El Gamal/ Diffie-Hellman and we will discuss which security properties are usually required from them nowadays. Subsequently, we will investigate the problem of secure multi-party computation, which studies how to "compute on encrypted data": how several mutually distrustful parties can collaborate to jointly perform computations involving private data without needing to actually reveal their private information to others. We will show how to develop secure optimization and machine-learning algorithms.

Important information concerning PhD courses:
We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 3.000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately four months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.
