Blog2: Second Priority Ideas
1. I am phasing out my old GMX e-mail address, so please update your address books.
2. The views expressed are my own and not necessarily those of my employer.
Short Biography
I am a research expert at SAP Research in Karlsruhe, Germany. Currently I am also temporary professor (Lehrstuhlvertreter) for the chair of privacy and data security at the Technical University Dresden. Before SAP I have worked for Siemens, the San Francisco-based startup Arxan, Intel and Digital Equipment in the job functions of project manager, software architect, and developer. I hold a Ph.D. in computer science from the Karlsruhe Institute of Technology, a master's degree from Purdue University, and a bachelor's degree from Berufsakademie Mannheim.
Research Interests
I research security and privacy algorithms and protocols for the next-generation, cross-organizational business applications. The challenge in my research is to balance the three objectives of security, performance and accuracy / utility / functionality. I have built systems for secure computation of cloud-based, collaborative benchmarking [4] and supply chain management [2] (in collaboration with the SecureSCM consortium). This work includes the first optimizing compiler for secure computations [18]. I have also developed an authentication protocol [44] and a policy model [36] for the secure exchange of RFID tracking events.
