Remote updates of a gas turbine engine

A method comprising:

• receiving an update request for an engine control from an offboard system at a communication adapter of a gas turbine engine of an aircraft;
• confirming an authentication between the communication adapter and the engine control;
• applying a cryptographic algorithm using one or more parameters received and cryptographic information to decrypt one or more configuration items received at the communication adapter from the offboard system, wherein the cryptographic information includes a combination of received cryptographic information and previously stored cryptographic information;
• transferring the one or more configuration items received at the communication adapter from the offboard system to the engine control based on the authentication;
• and
• transmitting an update completion confirmation of the engine control from the communication adapter to the offboard system based on a confirmation message from the engine control.

A gas turbine engine of an aircraft, the gas turbine engine comprising:

• a fan section comprising a fan case;
• an engine control configured to monitor and control operation of the gas turbine engine in real-time;
• and
• a communication adapter mounted on the fan case, the communication adapter comprising processing circuitry configured to:
• receive an engine control update request from an offboard system;
• confirm an authentication between the communication adapter and the engine control;
• apply a cryptographic algorithm using one or more parameters received and cryptographic information to decrypt one or more configuration items received at the communication adapter from the offboard system, wherein the cryptographic information includes a combination of received cryptographic information and previously stored cryptographic information;
• transfer the one or more configuration items received at the communication adapter from the offboard system to the engine control based on the authentications;
• and
• transmit an update completion confirmation of the engine control to the offboard system based on a confirmation message from the engine control.
