Secure wake-up method, wake-up authentication code generation and updating method of a network device and a network control device in a wireless body area network

摘要

A network device and a network control device in a Wireless Body Area Network (WBAN), and a secure wake-up method and a wake-up authentication code (WAC) generation method of the network device and the network control device are provided. The network device includes a wake-up circuit to receive a wake-up radio signal from a network control device using a Radio-Frequency Identification (RFID) receiver, to compare a WAC contained in the received wake-up radio signal with a WAC stored in advance, and to determine whether to wake up a main circuit unit, the network control device being contained in the WBAN; and the main circuit unit to be woken up in response to an interrupt signal from the wake-up circuit.
