has been held as an important part of WORLDCOMP:
Protecting the confidentiality and integrity of FPGA is of significant concern in electronics markets as FPGAs are coming into common use in the commercial, industrial and other field of products. Since the configuration information of FPGA is just an electronic data stream, it can be easily eavesdropped and tampered on the data bus or network. Such security issues are clearly hindering the use of partial reconfiguration systems, where users can download favorite circuits from the Internet on demand.
Of course the current high-end FPGAs have cryptographic cores to counteract such security issues, but in 2011, it was reported that the encryption key embedded in the FPGA was successfully extracted by side-channel attack. This success of the attack indicates that, with state-of-the-art techniques, the fixed key in non-volatile memory can be the flaw of the security-sensitive systems.
To tackle such security issues, Physical Unclonable Functions (PUFs) have been gathering wide attention. Silicon PUF is a circuit to generate a unique ID by using the device variation. The generated ID is to say a volatile secret, and no secret information need to be stored in the device. This talk will first introduce the security issues in the modern LSI markets, and then presents how PUF can solve the problems of FPGA security.
Yohei Hori is a research scientist at the National Institute of Advanced Industrial Science and Technology (AIST), Japan. He received the PhD (2004) in engineering from the University of Tsukuba, Japan. He spent the first five years after PhD as a postdoctoral researcher in AIST and developed various dynamically reconfigurable systems with FPGAs. He moved to Chuo University as a research scientist in 2009 and worked on the hardware security including side-channel analysis and physical unclonable functions. He moved back to AIST in 2010 and worked as a member of the SASEBO development team, which is the most popular side-channel evaluation board used in more than 30 countries in the world. His current research interest includes the partially reconfigurable systems, side-channel analysis, fault analysis and physical unclonable functions.
