1. A communication adapter of a gas turbine engine of an aircraft, the communication adapter comprising:
a communication interface configured to wirelessly communicate with an offboard system and to communicate with an engine control of the gas turbine engine;
a memory system; and
processing circuitry configured to:
receive one or more configuration items from the 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 the one or more configuration items, wherein the cryptographic information includes a combination of received cryptographic information and previously stored cryptographic information; and
transfer the one or more configuration items to the engine control based on the authentication.
