You're missing the bigger question: why? Encryption adds greatly to the coffee shop's cost. There are small one-time costs incurred when someone has to configure the access points, assign passwords, manage them, change them, post signs saying "this week's password is C0ffeebuck$" etc. There is an ongoing high payroll cost, too. Baristas are paid to ...
Even with WPA2/AES, someone can see the password, or if that is not possible, here is a simple way:- See some people who come around daily. Get some backdoors or rootkits for them. It would require skill but anything on same network/file share can be hacked. Go in, connect to your internet, get the key, and voila. As simple as that. So no amount of ...
For you custom app, you can bundle the public keys into the app, and keep the private key on your custom device. You're already distributing an application, so including the key with it is no big deal.
Make sure you adjust the number of deauths to send.. android devices can get deauth after sending 3-18 consecutive deauth, Linux devices get deauth after 10-30 deauths. IDK with windows.. you gotta test it by yourself.. just add the "-0" that's a zero followed by [number of deauth attack]
This answer assumes that the adversary does have access to run-of-the-mill scanning direction finders (an example). Also, the adversary is sure to detect your transmission (otherwise, you'd be talking about LPI radio comms). For a "successful" transmission without being pinpointed to a single (true) location with some guaranteed accuracy, you have to know, ...
There is no way to transmit data wirelessly without being susceptible to trilateration (using the standard definition of "radio wireless"). That's why attempts to "transmit data without revealing your location" usually end up shifting to things like laser, infrared, or other visible light methods. These things tend to work well in directional applications, ...
If you plug a switch into the wall there and plug multiple computers/devices into the switch you will be able to see multiple MAC addresses on that network port. If you plug a NAT device (home router) into the port and plug everything into the NAT device, it will look like the NAT device is the only thing plugged in from the upstream switch's point of view ...
If you are lucky enough to own Fyodor's Nmap Network Scanning book, then you will have a chapter dedicated to this question: "8.8 SOLUTION: Detect Rogue Wireless Access Points on an Enterprise Network", p. 202. While you cannot detect all access point with 100% certainty, you should be able to detect most of them by scanning and searching toward most common ...
You could also look into NFC only communication to transmit. That way you can corral the user into an area and have a good look. This would prevent the MITM part. Trunk out the lines into multiple stations and you can have drop points for the data.
Won't WPA+802.1X solve this? AFAIK, this means that no client can sniff the others' packets. I'd recommend that you double-check this before moving forward, but that's what I've understood from some brief re-reading (I haven't used 802.1X in years).
