Blockchain enabled aircraft secure communications

A method of transmitting data comprising:

• receiving, by a transceiver, a block from an originating aircraft wherein the block includes a data, a hash and a prior hash;
• determining, by a processor, a validity of the block in response to a blockchain register stored on a memory, the hash and the prior hash;
• determining, by the processor, a consistency of the data in response to an airspace map stored on the memory;
• determining, by the processor, a network consensus of the validity of the block;
• generating, by the processor, an updated blockchain register and an updated airspace map in response to the validity of the block, the network consensus and the consistency of the data;
• and
• controlling, by an aircraft controller, a host aircraft in response to the updated airspace map.

A distributed fleet communications method comprising:

• receiving a block from an originating aircraft include a data, a hash and a prior hash, wherein the data includes a position of the originating aircraft;
• validating the block in response to the prior hash and a blockchain register;
• determining an inconsistency between the position of the originating aircraft and a prior position of the originating aircraft;
• rejecting the block;
• and
• transmitting an indication of the inconsistency to the originating aircraft.
