One area where there is a need for an integrity and
authentication only suite is in amateur radio systems. In
amateur radio, any encoding scheme which hides the meaning of a
message is against the FCC regulations. However, remote control
by radio could benefit from both integrity and authentication.
The FCC regulations recognize this need and permit encryption of
messages controlling amateur radio satellites.
Amateur radio digital protocols include some state of the art
error detection and correction techniques, providing a kind of
integrity, but they do not provide authentication. Amateurs have
gotten by with a combination of very primitive authentication
techniques and legal action after tracking attackers with radio
direction finding.
While I'm not sure that this application area is important
enough to be addressed by the TLS working group, if there are
other application areas with similar needs, then perhaps these
needs should be addressed.
