Individual Research Cooperation between SecEng and Yale University, New Haven, USA

Since 2014, Prof. Stefan Katzenbeisser (CYSEC PI and Head of the Security Engineering Group SecEng) and his team have had a close working relationship with the research group of Jakub Szefer from the Computer Architecture and Security Lab (CASLab) at Yale University in New Haven, Connecticut, USA. The two partners cooperate in the area of hardware-related security with an emphasis on Physically Unclonable Functions (PUFs) and covert channels. The participants engage in the development of new PUF designs, which can be found in standard hardware components and can serve as low-cost security anchors, and the analysis of covert channels by electromagnetic emissions, which can be used by attackers to exfiltrate data even from high security computing systems. First results on practical PUFs utilizing physical characteristics of Dynamic Random Access Memory (DRAM) were presented at the Conference on Cryptographic Hardware and Embedded Systems (CHES) in Santa Barbara, California, USA in August 2016.

The cooperation is supported by Collaborative Research Center CROSSING as well as a DAAD (German Academic Exchange Service) grant.
