Abstract
Techniques for exchanging secure FTM messages are disclosed. An example of a wireless transceiver system for providing a secure Fine Timing Measurement (FTM) exchange includes a memory and a processor configured to obtain a initial-secure-token value and a secure-token-response value via an out-of-band signal, generate a FTM Request message including the initial-secure-token value, a transmitter to send the FTM Request message to a responding station, and a receiver to receive a FTM Response message including the secure-token-response value from the responding station, such that the at least one processor is configured to determine a Round Trip Time (RTT) value based at least in part on the FTM Response message.
