tion engine. However, this solution typically
includes stringent schedule and
program risk. Because of this, commercial
AES encryption is becoming more
popular. For onboard recording, the
NSA's Commercial Solutions for Classified
program (CSfC) has defined several
approved solutions for onboard recorders
or data-at-rest applications.
For RF telemetry data-in-transit, some

organizations have used AES-256
encryption. Custom solutions have
been designed for streaming flight test
telemetry using AES-256 encryption
engines and include forward error correction
to stream RF telemetry for all of
the RF links.
Data Latency
Encryption can compound another
issue: data latency within the FTI system.
On the aircraft, this includes the delay
introduced by data acquisition, PCM
frame conversion, encryption, and

to a display is based on the distance
of the link and the processing time on
the ground (including decryption, conversion
into engineering units, and final
distribution to ground operators).
