Daniel Slamanig

Researcher in Cryptography

AIT Austrian Institute of Technology

I am a scientist at AIT Austrian Institute of Technology in Vienna, Austria. Before joining AIT, I held a senior researcher position (2015-2017) and a postdoc position (2012-2015) in the cryptology and cryptographic security group at Graz University of Technology and a research associate position (2011-2012) at Carinthia University of Applied Sciences. I received a PhD degree (Dr.techn.) in computer science with distinction from AAU in 2011. My main research interests are in the field of cryptography and privacy with a focus on practical public key cryptographic primitives, privacy-preserving cryptography, their foundations and their applications in emerging fields such as cloud computing and the Internet of Things (IoT). I am a member of the International Association for Cryptologic Research (IACR) and the Austrian Computer Society (OCG).

I am one of the designers of the Picnic family of post-quantum digital signature schemes, a candidate submitted to NIST's post-quantum crypto standardization project.

This Winter Term (2018/2019) I am teaching Introduction to Modern Cryptography at TU Wien (192.062 and 192.063) jointly with Krzysztof Pietrzak. See here for further information on my part of the course.

I am looking for a motivated Ph.D. student to work with me on exciting topics in cryptography! (see link for more information)
