FIELD: information technology.
SUBSTANCE: wireless network for monitoring a patient comprises a body sensor network that includes one or more wireless sensors connected to the patient that collect and transfer information related to the patient's health to the wireless network. A set-up server configures one or more wireless sensors with keying materials before one or more sensors are deployed to the wireless network. A base station distributes a key certificate to one or more sensors associated with the body sensor network, such that two sensors generate a unique pairwise key based at least in part on the pre-distributed keying material and the key certificate distributed by the base station.
EFFECT: more secure connection.
