Our paper "LocKey: Location-based Key Extraction from the WiFi Environment in the User’s Vicinity" got accepted at ISPEC 2023! In the paper, we describe an approach to reliably extract a location-based cryptographic key from the WiFi signals in a user’s immediate vicinity. The approach is very lightweight and does not require any user interaction. It can therefore be used in various application domains, for example, to extract a location-based secret key, which can be used to make known password-based authentication methods more secure.
