Abstract
This disclosure describes systems, methods, and computer-readable media related to testing tools for devices. In some embodiments, a plurality of public keys may be received from a server via a secured network connection where each of the plurality of keys corresponds to a respective private key associated with an access point. A time-of-flight (ToF) measurement protocol may be initiated with one or more access points. Data generated by ToF measurement protocol with the one or more access points may be received. In some embodiments, the one or more access points may be authenticated based at least in part on the plurality of public keys. A location of a user device may be determined based at least in part on the received data.
