Computer Science day

Computer Science day

Every year in February, we celebrate the Computer Science Day. The networking event invites all interested parties, RUB members, partners of the faculty and, of course, faculty members to spend an afternoon exploring computer science.

Researchers from the faculty present the latest state of their research in exciting short talks in an entertaining and understandable way. At the get-together afterwards, you can exchange ideas with the speakers and other participants, network and discover overlaps with your area of interest.

Wednesday, February 7, 2024, 2 PM – 6 PM

RUB campus, building MC, Open Space (directions, campus map)

Places are limited! Please register: Registration

The talks 2024

Have you ever heard of artificial intelligence (AI)? If so, you may have also heard of reinforcement learning. This is the primary technique behind DeepMind’s AlphaGo, the first AI system to beat the world’s best human Go players. Reinforcement learning promises that autonomous systems can learn to operate in unfamiliar environments with minimal human intervention. However, why haven’t most autonomous systems implemented reinforcement learning yet? The answer is simple: there are significant unsolved challenges. One of the most important ones is obvious: Autonomous systems operate in unfamiliar, unknown environments. This lack of knowledge is called uncertainty. In this talk, we will explore why making decisions that account for this uncertainty is essential to achieving trustworthy, reliable, and safe artificial intelligence.

Speaker: Prof. Dr. Nils Jansen

Does Energy Efficiency Compromise Security of Tomorrow’s Computer Systems?

Nowadays, energy has become a critical resource – especially for computer systems that affect our everyday lives. In an effort to minimize our energy consumption and reduce our carbon footprint, it is critical that we focus on reducing the energy demand of our systems. Regrettably, enhancing the energy efficiency of our systems often collides with the need to maintain security measures. Implementing extra security measures, such as software mitigations for hardware vulnerabilities, can lead to substantial overheads. This is observed, for instance, when analyzing the impact of these mitigations on system performance and efficiency.

At the same time, energy has become a critical resource that can be exploited as an attack vector, threatening system security. This can occur by draining the energy supply of embedded systems, making them inoperable, or by analyzing the power demand, which can leak crucial information about system operations.

This talk delves into the critical debate of whether security costs us energy or whether energy costs us security. It further explores adaptable operating-system architectures and their role in future computer systems.
Can we achieve a harmonious balance between energy efficiency and security simultaneously?
