In recent automotive vehicles, more and more functionalities are implemented in software. After-sales update of automotive software, which is often called reprogramming, is crucial in order to improve the safety and security of the vehicles. At present, software update is done at authorized garages, but it costs a lot of time and money. This talk describes our ongoing research project on remote update of automotive software. PUF (physically unclonable function) is utilized in order to realize remote software update in a secure and cost-efficient manner.


Professor Tomiyama received his B.E., M.E. and D.E. degrees in computer science from Kyushu University in 1994, 1996 and 1999, respectively. From 1999 to 2001, he was a visiting postdoctoral researcher with the Center of Embedded Computer Systems, University of California, Irvine. From 2001 to 2003, he was a researcher at Institute of Systems & Information Technologies/KYUSHU. In 2003, he joined the Graduate School of Information Science, Nagoya University as an assistant professor, and became an associate professor in 2004. In 2010, he moved to the College of Science and Engineering, Ritsumeikan University as a full professor. His current research focuses are on hardware/software codesign of manycore SoCs.
