Henrich C. Pöhls
Henrich C. Pöhls received his graduate diploma in computer science (Dipl. Inf.) from the University of Hamburg and additionally holds an M.Sc. in Information Security from Royal Holloway University of London. Ever since the late 1990s he was interested in IT security. Over a decade, since 2004, he is doing academic research: In 2004 he became a Research Assistant to Prof. Joachim Posegga, first at University of Hamburg and since 2008 at the University of Passau. He always enjoys pointing out the difference between information security, lets say encrypted communication, and practice, e.g. setting up openvpn. Thus, he devised and also delivered for many years a hands-on class at university and was teaching students how to apply theoretic concepts of computer and information security in practice. Henrich C. Pöhls current research focus lies on practical applications and legal implications of advanced digital signature schemes, such as malleable signatures. He has authored and co-authored many academic publications, especially on the topic of tailoring cryptographic signature primitives for making them legally compliant and making their privacy enhancing features suitable for an application in various domains ranging from supply chain documents, to data from the Internet-of-Things, to the cloud. He is keen on interdisciplinary work especially in the field of cryptography, software development and law, as he thinks the more gaps between those three worlds can be bridged the more sound (=safe, secure and legally compliant) ICT-enhanced products and environments like smarthomes or smartcities become. Henrich C. Pöhls leads the security work in several third party funded collaborative research projects: In ReSCUeIT he planned web services allowing the exchange authentic but trade-secret preserving documents in food supply chains; in the RERUM project he signed messages exchanged between the smart things in the Smart City, but allowed privacy enhancing redactions to protect the citizens' privacy rights, i.e. securing messages already for the device-to-device communication in the Internet-of-Things; in the PRISMACLOUD project he advances malleable signatures to become software libraries easy-to-use for developers in cloud environments and applies privacy- and security-by-design principles to make the cloud behave as the human user would expect.
