Deriving Cryptographic Keys from Physiological Signals and Biometrics

Body Area Networks (BANs) are the most important building block of pervasive healthcare. They provide effective, efficient and accurate monitoring of the vital body signals through the use of interconnected wearable biosensors, without disturbing the daily lives of the patients.
In BANs, security and the privacy of the data transferred are among themost important  requirements. BANs necessitate two types of secure communications: (i) intra-BAN and (ii) beyond-BAN communication. The former addresses the secure communication among the biosensors and the aggregating devices, while the latter defines secure data sharing over the central server. In this talk, we will overview a set of studies that we conduct aiming to generate pairwise cryptographic keys for both type of communication patterns of BANs using human body. For intra-BAN, a key derivation and agreement methodology using physiological signals (such as ECG, PPG, blood pressure) will be described. For beyond-BAN, a key agreement protocol based on fingerprints will be detailed.

Albert Levi is professor of Computer Science and Engineering at Sabanci University, Istanbul, Turkey and is currently on sabbatical, visiting  Dalhousie University, Faculty of Computer Science. He received B.S.,  M.S. and Ph.D. degrees in Computer Engineering from Bogazi├ži University, Istanbul, Turkey, in 1991, 1993 and 1999, respectively. He served as a  visiting faculty member in the Department of Electrical and Computer  Engineering, Oregon State University, OR, USA between 1999 and 2002. He  was also a postdoctoral research associate in the Information Security Lab of the same department. Since 2002, Dr. Levi is a faculty member of Computer Science and Engineering in Sabanci University. His research interests include computer and network security with emphasis on mobile and wireless system security, key distribution, public key  infrastructures (PKI), privacy, and application layer security protocols. Dr. Levi has served in the program committees of various international conferences. He also served as general and program co-chair of ISCIS 2006, general chair of SecureComm 2008, technical program co-chair of NTMS 2009, publicity chair of GameSec 2010 and
program co-chair of ISCIS 2011. He is editorial board member of The Computer Journal published by Oxford University Press and Computer Networks published by Elsevier.
