Abstract
Techniques for providing a secure Fine Timing Measurement (FTM) exchange between two wireless transceivers are disclosed. An example of a method according to the disclosure include transmitting a protected FTM range request message with a Dialog Token of a FTM frame, receiving a protected FTM range report message from a station, wherein the protected FTM range report message includes FTM information, and authenticating the station based at least in part on the FTM information included in the protected FTM range report message.

A method for providing a secure Fine Timing Measurement (FTM) exchange between two wireless transceivers, comprising:
- transmitting a protected FTM range request message with a Dialog token of a FTM frame;
- receiving a protected FTM range report message from a station, wherein the protected FTM range report message includes FTM information;
- and
- authenticating the station based at least in part on the FTM information included in the protected FTM range report message.
A method of participating in a secure Fine Timing Measurement (FTM) exchange with a mobile device, comprising:
- receiving a protected FTM range request message including a Dialog token of a FTM frame;
- transmitting a FTM request message;
- receiving a plurality of FTM messages;
- determining that a Dialog token included in a FTM frame in the plurality of FTM messages matches the Dialog token included in the protected FTM range request message;
- determining a FTM timing information based at least on one of the plurality of FTM messages;
- and
- transmitting a protected FTM range report message including the FTM timing information.
A system for providing a secure Fine Timing Measurement (FTM) exchange between two wireless transceivers, comprising:
- a memory;
- at least one processor operably coupled to the memory;
- a transceiver operably coupled to the memory and the at least one processor, and configured to:
- transmit a protected FTM range request message with a Dialog Token of a FTM frame;
- receive a protected FTM range report message from a station, wherein the protected FTM range report message includes FTM information;
- and
- wherein the at least on processor is configured to authenticate the station based at least in part on the FTM information included in the protected FTM range report message.
A client station for participating in a secure Fine Timing Measurement (FTM) exchange with a mobile device, comprising:
- a memory;
- at least one processor operably coupled to the memory;
- a transceiver operably coupled to the memory and the at least one processor, and configured to:
- receive a protected FTM range request message including a Dialog token of a FTM frame;
- transmit a FTM request message;
- receive a plurality of FTM messages;
- wherein the at least one processor is configured to:
- determine that a Dialog token included a FTM frame in the plurality of FTM messages matches the Dialog token included in the protected FTM range request message;
- determine a FTM timing information based at least on one of the plurality of FTM messages;
- and the transceiver is configured to
- transmit a protected FTM range report message including the FTM timing information.
