Had a great couple of days USENIX Security. Met lot of "old" friends and new talents. Happy to report that my voice is slowly recovering. Thanks to our friends from CASA - Cluster of Excellence for Cyber Security for the CASAfants - they were immediately adopted by my girls and are having a good time.

Ben Stock USENIX Security casafant Now we wonder who got to the cheese first? When this CASAFant saw the photo, he also wanted to play with a mouse, but somehow it went differently than he thought.

Yesterday, Patrick Neumann presented our paper "On Perfect Linear Approximations and Differentials over Two-Round SPNs" (joint work with @ChristofBeierle, Patrick Felke, Gregor Leander, and @LukasStennes) at CRYPTO. casafant enjoyed the talk!

Toot toot! As CEO of CASA - Cluster of Excellence for Cyber Security (sorry @ExcCasa, it's Chief Elephant Officer now), I approve of Veelasha Moonsamy (@veelasha.bsky.social)'s message at the iMentor workshop: Early-career researchers should definitely come talk to me at our ACM CCS 2025 booth and get more info to join Ruhr-Universität Bochum!
