Physiological Signal Based Security
Body Area Networks (BANs) are inherently cyber-physical systems which interact with the human body by using sensors to collect, process and communicate health data (vital signals, temperature, pressure) from the person. This information from the environment that is already being collected can be used to provide security to the BAN. Physiological Value based Security (PVS) uses the vital signals of the human body that is collected during health monitoring operation to provide usable security to BAN. Properties of PVS For PVS to succeed the scheme developed should have the following properties: # The keys provided by PVS for security are long and random (a basic requirement in any security protocol). # Knowing the physiological signals at any time will not provide significant advantage in knowing the keys agreed upon in future executions of the scheme, i.e. time variance (required to prevent attacker from guessing future feature values from present ones). # The physiological st ...
