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.
