There's a very amusing epilogue in Steven Levy's "Crypto" [0] about the fact that either RSA or Diffie-Hellman (I've forgotten which) was in fact known to the intelligence services for 10+ years prior to its re-discovery among public researchers. These are people who are very good at keeping secrets.

Both, but neither for as long a period of time beforehand as you remember.

Aha! Good correction, thank you. I must have been remembering how long the discovery remained classified, not how long it predated the public discovery.
