    • A wireless sensor network for wirelessly monitoring a medical subject includes a plurality of sensor nodes (22, 24, 26, 122, 124, 126). Each sensor node includes a wireless transceiver (46) for sending and receiving wireless messages, a sensor (40, 42, 130, 132, 140, 142) monitoring a characteristic of the medical subject, and a processor (50). The processor is programmed to at least perform an authentication method including: (i) acquiring sensor data via the sensor for a predetermined time (76) responsive to receiving a wireless trigger message; (ii) storing an association code (60, 150, 152, 160, 162) computed from the acquired sensor data; and (iii) authenticating a subsequently received wireless message containing an association code tag by comparing the association code tag with the stored association code. The processor further attaches the stored association code as the association code tag in messages sent to other sensors.
    • 用于无线监测医疗对象的无线传感器网络包括多个传感器节点(22,24,26,122,124,126)。 每个传感器节点包括用于发送和接收无线消息的无线收发器(46),监测医学对象的特征的传感器(40,42,130,132,140,​​142)以及处理器(50)。 处理器被编程为至少执行认证方法,包括:(i)响应于接收到无线触发消息,经由传感器获取传感器数据达预定时间(76); (ii)存储从获取的传感器数据计算的关联码(60,150,152,160,162); 以及(iii)通过将所述关联代码标签与所存储的关联代码进行比较来认证随后接收的包含关联代码标签的无线消息。 处理器还将存储的关联代码作为关联代码标签附加到发送到其他传感器的消息中。
