Cryptologic Spectrum was a cryptology journal published internally by the NSA. The journal was first published in 1969, until consolidation with the NSA Technical Journal in 1981. A selection of articles published between 1969 and 1981 are available to the public online.
The journal had been classified until its tables of contents were published online in September 2006 following a Freedom of Information Act request in 2003.
Cryptologic Quarterly was the combined result of the merger of NSA Technical Journal and Cryptologic Spectrum in 1981. CQ as it is sometimes known by, expanded its coverage to cover a larger segment of NSA readership.
The tantalizing tables of contents to the best spy magazines you'll probably never get to read have been posted online, thanks to a Freedom of Information Act request that pried open four classified National Security Agency publications.
Written specifically for NSA employees, the articles listed in the online indexes date back as far as 1956. Stories include an analysis of the TRS-80 Model 1's password-encryption algorithm, accounts of how Soviet codes were broken, analyses of bad management techniques within the sprawling eavesdropping agency, and an insider's view of North Korea's capture of the spy boat U.S.S. Pueblo in 1968.

I skimmed through the report and find it very interesting.
A question that kept arising was, Why was it ever top secret?
