Cryptography and Cryptanalysis Articles, Volume 2
The companion volume to Aegean Park Press's Cryptography and Cryptanalysis Articles, Volume 1: a second gathering of previously classified cryptology articles originally printed in the Army's Signal Corps Bulletin, edited by William F. Friedman and issued in 1976 as No. 6 in the publisher's Cryptographic Series (Volume 1 was No. 5).
Bookseller listings for this volume were found to be inconsistent, several apparently reusing Volume 1's article list and description rather than describing this book's actual contents. No source consulted could be confirmed as describing Volume 2's specific articles independently of that overlap, so this record does not assert which pieces it contains. What can be said with more confidence is the shared premise of the series: the publisher's stated purpose was to collect Signal Corps Bulletin articles on cryptography and cryptanalysis, most previously classified, into single volumes as collateral reading for students of the field.
