Secure data transmission and processing using the ARINC 629 protocol

摘要

The security procedure operates by launching two independent computing processes (M1 and C1) and testing the coincidence of the ending of these processes. When this is confirmed, the system launches, in a sequence specific to the application, a non-consolidated intermediate action for each of the two sequencing processes. After the temporal coincidence of these intermediate actions has been detected priority external events are taken into account, and a resulting action is produced if all necessary conditions are satisfied. The two computing processes are triggered from the same incident asynchronous signal.
