ENCRYPTION AND SECURITY IN A DISTRIBUTED CONTROL NETWORK

摘要

Methods and systems are provided for controlling a component of an aircraft engine (112) by communicating data over an inner control loop portion (118) of a distributed engine control network (102) for an aircraft (202); and controlling an operation of the aircraft engine (112) by communicating encrypted data over an outer control loop portion (120) of the distributed engine control network (102), wherein the data communicated over the inner control loop portion (118) is unencrypted or encrypted with weaker encryption than the data communicated over the outer control loop portion (120).
