Collaboration site for the RYWA Avionics Attestation Project for assurance that target aircraft will start in a known-good state.

What is TAP?

As part of pre-flight checks, technicians use a trusted external verifier to validate the contents of non-volatile storage on-board the LRU. The program uses strict timing analysis and queries to identify anomalies. As a result, operators can generate assurance that the target aircraft will start in a known-good state. During the static attestation process each memory area is scanned and memory contents and response times are recorded and compared against expected values. Any unauthorized changes to OFP are detected and errors or possible cyber-attacks are displayed on the operator GUI.
