Systems and methods for third-party time and position authentication

A transceiver device, comprising:

• one or more memories;
• and
• one or more processors, communicatively coupled to the one or more memories, configured to:
• receive an overt data sequence and a covert data sequence indicative of received spectra of a signal over which the overt data sequence is transmitted;
• derive, from the overt data sequence, an overt time and position solution indicating a position of the transceiver device and a time at which the transceiver device was at the position;
• record an in-phase-quadrature phase (I/Q) spectrum recording of the covert data sequence;
• digitally sign a unique identifier of the transceiver device, the overt time and position solution, and the I/Q spectrum recording to create a unique data representation of the unique identifier, the overt time and position solution and the I/Q spectrum recording;
• and
• provide the unique data representation to be entered into an unauthenticated distributed ledger entry of an unauthenticated distributed ledger.

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of an authentication equipment, cause the authentication equipment to:
• receive an in-phase-quadrature phase (I/Q) spectrum recording of a covert data sequence indicative of received spectra of a signal over which an overt data sequence is transmitted and an overt time and position solution, derived from the overt data sequence, indicating a position and a time at which the position was derived;
• process the I/Q spectrum recording to derive an independent time and position solution indicating a position where the I/Q spectrum recording was recorded and a time at which the I/Q spectrum was recorded at the position;
• determine, based on comparing the overt time and position solution and the independent time and position solution, whether the overt time and position solution and the independent time and position solution are a match;
• and
• authenticate the overt time and position solution based on the overt time and position solution and the independent time and position solution being a match.
