Security and Privacy Lunch

People interested in network security and privacy meet regularly over lunch break and discuss very recent research related to security and privacy from high-quality scientific conferences (IEEE Security and Privacy, ACM CCS, NDSS, NSDI, USENIX Security, ACM SIGCOMM, ...). This is a great way to spend your lunch break and keep pace with cutting edge security and privacy research. Talking about scientific presentations often leads to interesting new ideas, possibly laying the foundation for your future thesis topic.

With most restrictions regarding the pandemic lifted, we return to bi-weekly sessions in our seminar room. Join our mailing list to receive updates.
