The intention is to use non-plaintext (but technically not encrypted) authentication without TLS over ham frequencies. Hashed challenge/response auth methods don't violate the FCC rules. Of course, without TLS encryption, the auth process is not totally secure. And, yes, the message itself would be in plain text. But it's the best we can do given the rules. Think of it as packet radio on steroids. 73, Michael N6MEF

KSB:> Just curious, it is transferred in some RSxxx serial protocol?The expectation is that the unencrypted traffic will be used for clients on an Ethernet network behind a radio operating on amateur radio frequencies according to FCC Part 97 rules. The radio could be: -- 56+kbps UHF, such as the upcoming UDRX-440 by NW Digital Radio -- WiFi radio using BBHN or AREDN mesh software -- WiFi radio using commercial software, but operated under FCC Part 97 (amateur radio) rules, instead of Part 15 (commercial/consumer) rules -- ... or maybe something else It won't be the bulk of our traffic, but it is important since it is part of the county's emergency communications plan. I don't want to hijack this list with amateur radio stuff. Curious hams can contact me off list at n6mef at mefox dot org. Michael
