I don't know about a single algorithm but one attempt was to provide black
boxes under the CCEP that accepted a key and plaintext/ciphertext and spat out
ciphertext/plaintext. The CCEP gear would be non-exportable, thus solving the
DES problem where either US banks/corporates could export it or you could buy
foreign gear built to the publicly-available design. Since it never survived
into production several aspects of it were rather unclear, but it looked like
the NSA would be a middleperson in the key management process.
