SLEEP DENI ATTENDANCE RADIO RECEIVING / RECEIVING DEVICE RESISTANT TO SLEEP DENI ATTACKS

摘要

The present invention relates to a wakeup radio transmitting / receiving device for a resource-constrained node such as a loT network node. The device comprises an auxiliary circuit, permanently powered, adapted to detect a wake-up code, and a main circuit, normally in the standby state and which is activated by the auxiliary circuit when a wake-up code is detected. The next wake-up code is calculated by the main circuit by applying a one-way function to at least a portion of a message exchanged on the main radio by means of secure communication.
