Method and system for remote load of on-board certified software

A non-transitory computer-readable medium having stored thereon, computer executable instructions that, if executed by a computing device, cause the computing device to perform a method for remotely uploading certified software from a source to a data update logic on an asset via a wireless communications link comprising:

• encrypting the wireless communications link between the source and the data update logic to form a secure tunnel;
• autonomously verifying a credential of the source at the asset when a software update file is transmitted based on an authorized credential preloaded onto a storage device in the asset;
• performing a load assurance check on a portion of the transmitted software update file to confirm integrity of the transmitted software update file after the credential of the source is verified, wherein the load assurance check calculates a cryptographic hash function for comparison to a check value provided by the source;
• and
• activating the transmitted software update file after the transmitted software update file integrity is verified, the activating occurring automatically in a data processing module and being devoid of human intervention, the asset being an aircraft.

A system for remotely updating software from a source to an aircraft comprising:

• a processor;
• a memory within the aircraft, the memory storing machine-readable instructions that, when executed by the processor, cause the processor to:
• receive a file transmitted from the source and representative of a software update;
• a wireless communications link forming an encrypted tunnel between the source and the memory;
• and
• the memory storing machine-readable instructions that, when executed by the processor, cause the processor to:
• autonomously verify a credential of the source when the software update file is transmitted based on an authorized credential preloaded onto a storage device in the asset;
• perform a load assurance check on a portion of the transmitted software update file to confirm integrity of the transmitted software update file after the credential of the source is verified, wherein the load assurance check includes a comparison between a cryptographic hash function and a check value provided by the source;
• and
• activate the transmitted software update file after the software update file integrity is verified, the activating occurring automatically in a data processing module and devoid of human intervention.
