NSA has released under FOIA nine crypto docs in response to a request
for information on "Non-Secret Encryption" and JH Ellis. One is a formerly
secret paper by Ellis written in 1977. Another is a formerly confidential
paper by Clifford Cocks written in 1998. Ellis and Cocks were long
associated with CESG.

Three of the nine papers were formerly classified as Top Secret Codeword.
