Abstract
A transmission/reception device with wake-up radio for a node with limited resources such as an IoT network node. The device includes a permanently powered auxiliary circuit, capable of detecting a wake-up token, and a main circuit, normally in the idle state and activated by the auxiliary circuit when a wake-up token is detected. The next wake-up token is calculated by the main circuit by applying a one-way function to at least part of a message exchanged on the main radio through a secure communication.
