Jesko Dujmovic
Hello, I'm Jesko Dujmovic, well technically Dujmović, but I prefer Dujmovic. It is easier to type and does not break any forms.
I'm currently a PhD candidate with Nico Döttling at CISPA. I'm generally interested cryptography, preferrably theoretical cryptography, but I also love to see protocols deployed in real life. More specifically, I love working on Private Information Retrieval, Time-Lock Puzzles, obfuscation, idealized models, proof systems, and so much more.
I'm always down for a conversation about cryptography, so if you see me at a conference just talk to
me. There should be a picture of me on this website. You can also email me at
jesko . dujmovic @ cispa . de or find me on Xitter. If you are looking for a good conversation starter
with me ask me about my opinions on the random oracle model.
