> Our software had the ability to assign MACs to interfaces for a little while now, and as a response to this study we've now also added MAC randomization, now in the dev branch […] Will it follow what the IEEE is proposing? * 802.11bh: Enhanced service with randomized MAC addresses * 802.11bi: Enhanced service with Data Privacy Protection * https://standards.ieee.org/beyond-standards/data-privacy-and-ease-of-use-in-wireless-networks/ https://standards.ieee.org/beyond-standards/data-privacy-and...

These amendments might not apply to BSSIDs/Access Points but refer to enhanced privacy features to stop the fingerprinting of stations as well as providing ways for APs to identify stations under randomization, across a complicated network.

That section of the paper states: Although there are already various ways to improve security and privacy, IEEE 802.11bf is still discussing which solution to add. Hopefully the scheduled 2025 launch of 802.11bf will be gated upon _implementation_ of security and privacy. > Of course Wifi sensing is already a thing with existing signals Several orders of magnitude exist between researchers and commercial devices in the hands of millions of consumers.
