Current Activities

Henrich C. Pöhls currently lectures in IT-Security, i.e General IT-Security as well as Secure AI Systems, and in his teaching and research he tries to bridge gaps by conducting interdisciplinary work especially in the fields of IT-Security (esp. cryptography), software development and law:

"The more gaps between those worlds get bridged, the more sound (=safe, secure and legally compliant) ICT-enhanced products and digitally-enhanced environments will be."

Besides teaching he collaborated and lead several successful research projects on security and privacy for Cloud (eg. PRISMACLOUD) & IoT (eg. RERUM and SEMIoTICS). Finally, he is also active in national and international standardisation (eg. editor of ISO/IEC standard 23264 on Redaction of authentic data in ISO JTC1/SC27).

Research Interests

Secure AI Systems (increasing the IT-security of AI systems and risk analysis of systems that incorporate AI functions)
Integrity protection (legally, cryptographically, organisationally),
Redactable & Sanitizable Signatures,
Legal implications of Digital Signatures (EU Electronic Signature Legislation - eIDAS),
Privacy Enhancing Technology (PET) and Data Protection with respect to Authenticity and (Structural) Integrity Protection of the contained Information,
Security of Internet-Of-things (IoT),
SupplyChain- / SOA- / BusinessProcess-Security,
Digitally Signed Microformatted Content and
Tree-Based Structured Document Formats (XML-Based).
Additional interests:
- Web-Services, "Web 2.0"
- Wireless Communications (WLAN, Bluetooth, RFID, etc.)
- TLS, PKI, and Certificates
- Networked Smartcards
