Christoph Striecks

I am a cryptographer with a professional focus on secure technologies demanded by real-world applications (such as end-to-end security, secure data access control, and authentication). Moreover, I am particularly interested in long-term security (e.g., forward security) and hybridization techniques towards scalable quantum-safe systems.

Before joining the AIT Austrian Institute of Technology – Austria’s largest Research and Technology Organization (RTO) – in 2016, I held a post-doc position at the Karlsruhe Institute of Technology (KIT) in Germany.

In 2015, I received my PhD (Dr. rer. nat.) in cryptography from KIT under the supervision of Prof. Dennis Hofheinz (now at ETH Zurich) on scalable advanced cryptographic building blocks. Teaching activities included Algorithms I (lab, ST 2015) and IT security (lab, ST 2013), encompassed by several seminars and labs.

In 2010, I received my Diploma in computer science from the Technical University of Braunschweig in Germany with a major in cryptography and software engineering. From March to September 2008, I worked as a software-development intern for Siemens USA in Princeton, New Jersey.
