摘要
A wireless network (2, 150) for monitoring a patient includes a body sensor network (22, 24, 26, 172, 174, 176) that includes one or more wireless sensors (6, 8, 10, 12, 14, 16, 18, 20, 156, 158, 160, 162, 164, 166, 168, 170) operatively connected to the patient that collect and transfer information related to the patient's health to the wireless network (2, 150). A set-up server (4, 154) configures the one or more wireless sensors (6, 8, 10, 12, 14, 16, 18, 20, 156, 158, 160, 162, 164, 166, 168, 170) with keying material before the one or more sensors (6, 8, 10, 12, 14, 16, 18, 20, 156, 158, 160, 162, 164, 166, 168, 170) are deployed to the wireless network (2, 150). A base station (178, 180) distributes a key certificate to the one or more sensors (6, 8, 10, 12, 14, 16, 18, 20, 156, 158, 160, 162, 164, 166, 168, 170) associated with the body sensor network (22, 24, 26, 172, 174, 176), such that two sensors generate a unique pairwise key based at least in part upon the pre-distributed keying material and the key certificate distributed by the base station (178, 180).
