[Cryptography] The agency that came in out of the cold

[Robert Wilson]

Reminded by the "NSA ex-Top Secret Umbra document": A couple of decades 
ago, at the annual national meeting of the American Mathematical Society 
(and the then more separate Mathematical Association of America), there 
was a talk titled something very close to "The Agency That Came in Out 
of the Cold". I cannot even remember which year. I'd like to be able to 
get back to that, e.g. if there were a copy of the talk in one of the 
AMS journals, but so far have not found such. Any leads? It was 
completely open to the world (other than having to come to the meeting).

I was very much reminded of it by the discussion of relations between 
the agency and academia, in that paper. Many of my friends were on the 
academic side of that debate, but at the same time many of them still 
feel they should not talk about that work.
