This was just one tiny EU research project with limited funding, which was focused only on passive attacks, e.g. a receiver with custom firmware can make inferences from existing Wi-Fi routers. Their research was looking for a way to modify the default behavior of Wi-Fi transmitters to reduce leakage of location information. If this was the default behavior (e.g. via some combination of IEEE standard and regulation), then active attackers could be easily identified. https://ans.unibs.it/projects/csi-murder/ https://ans.unibs.it/projects/csi-murder/ > this paper addressed passive attacks, where the attacker controls only a receiver, but exploits the normal Wi-Fi traffic. In this case, the only useful traffic for the attacker comes from transmitters that are perfectly fixed and whose position is well known and stable, so that the NN can be trained in advance, thus the obfuscator needs to be installed only in APs or similar ‘infrastructure’ devices. Active attacks, where the attacker controls both the transmitter and the receiver are another very interesting research area, where, however, privacy protection cannot be based on randomization at the transmitter. More research and funding is needed.
