There's an interview with Simmons somewhere (I cannot find it now), where
he recounts being aware of the PK codes and having thought about their
application to nuclear test telemetry before the Hellman/Diffie paper
(maybe RSA report). When he saw an unclassified description of PK codes,
he immediately sat down and wrote up his thoughts---and could base them on
unclassified sources.
