Abstract: Methods and systems for authenticated wake-up radio frames are disclosed. In one aspect, a method includes generating a wake-up radio (WUR) integrity group key (IGTK) for authentication of WUR frames when received by a wake-up radio (WURx). The WUR IGTK may be identified via a key identifier in the WUR frame. The key identifier may be updated when the WUR IGTK is updated, facilitating WUR IGTK key updating across multiple associated stations.
