Knowles is certainly Stev Knowles -- haven't reached him but found
a co-conspirator. Attached note sent with permission.

ah, the sins of ones youth that never seem to be lost...
it was something that ben levy and stev and i did at ftp many
many moons ago. bridgham and stev were the instigators of it.
the idea was simple, put a dh key exchange directly in tcp
so that all tcp sessions could be encrypted without requiring
any significant key management system. authentication was not
a part of the idea, it was to be provided by passwords or
whatever, which could now be transmitted over the internet
with impunity since they were encrypted... we implemented
a simple form of this (doing the math was non trivial on the
machines of the day). it worked. the only failure that i
remember was that it was vulnerable to man-in-the-middle
why "skeeter" and "bubba"? well, that's known only to stev...
