Kathleen Philips - Program Director Perceptive Systems for the Internet of Things – Infrastructure and Person Centric, imec/Holst Centre

Dr. Kathleen Philips is a program director at imec/Holst Centre for infrastructure- and person-centric focused Perceptive Systems. Perceptive Systems build a view of the world, using the information from their own sensors, as well as information from the cloud.   Within this program, imec has been at the forefront of ultra-low power circuit and sensor design, with over 60 papers at ISSCC and IEDM and over 100 patents. In the IoT area, the research scope has been expanded including lightweight security for wireless sensors and new research on distributed and heterogeneous sensor networks, offering the innovations that will lead to an intuitive IoT. The multi-disciplinary team includes experts on ultra-low power radio, dsp and sensor design, as well as  on heterogeneous networking, distributed data analytics, edge security and testbed implementation.
Kathleen has joined imec in 2007 and has held positions as principal scientist, program manager for ULP Wireless and program director for Perceptive Systems. Before that time, she was a research scientist at Philips Research for over 12 years. She holds a Ph. D in electrical engineering, has authored and co-authored over 60 papers and holds various patents.




Presentation abstract

The Achilles Heel of IoT – On-power consumption and security in  IoT leaf Nodes

IoT is connecting a diversity of Things to the internet. These Things represent the senses of the internet and bring vision, sound, smell, taste  a.o. While these end nodes enable a rich and holistic picture of the Smart Home, the Smart City, a.o.; the end nodes also risk becoming the Achilles Heel of the IoT.
Despite of an amazing power reduction of wireless connectivity over the past decade, battery lifetime of the end nodes still limits the lifetime of the IoT network. New connectivity standards rely on heavily duty-cycled operation with long sleep periods in order to achieve 10 years of operation without battery replacement.  However, the use of long sleep periods brings new challenges on time keeping, memory organization, a.o.
Second, the low cost end nodes are considered the weak link in IoT security. These small and low cost devices are mostly under-protected and can, and will, be tampered.  Secure location awareness can be used as an additional authentication factor. If co-designed with the communication protocol, a low cost implementation becomes possible. Apart from authentication via a secure location estimate, it also offers new secure proximity services.
