Offered here is the first separate edition, as issued in the Bell Telephone System Monograph series (#1727: April 1950). We are unaware of any separately issued Bell System Technical Journal offprint for this paper.
"Shannon's insight, his great contribution to cryptology, lay in pointing out that [language] redundancy furnishes the ground for cryptanalysis. 'In ... the majority of ciphers,' he wrote, 'it is only the existence of redundancy in the original messages that makes a solution possible.' This is the very basis of codebreaking." (Kahn 1996, p 748)
"The discoverer of information theory examines cryptology in terms of that theory: redundancy, entropy, equivocation. Shannon develops formulas that enable the cryptanalyst to tell when a solution in a particular cipher system is valid. He discusses perfect secrecy (the absolutely unbreakable cipher) and ideal secrecy (practically unbreakable ciphers) and work characteristics needed to solve different kinds of ciphers. (Kahn 1969, pp 324-5)
"[Communication theory of secrecy systems] has provided, for the first time, a well-organized theory of cryptography and cryptanalysis, and it is highly regarded by the expert cryptanalysts." (Pierce, p 271)
PROVENANCE: none.

COLLECTORS NOTE: The Bell Telephone System Monograph series offered a way to obtain individual articles by Bell scientists regardless of where their work was first published. Many Monographs significantly postdate the original article publication. Because of this, they rarely constitute the coveted (and traditional) article offprint. If the journal of record issued no offprint, the Monograph might be the first separate publication - the closest the collector can come to a traditional offprint. We have done our best to place each Monograph properly in the article's publishing history and welcome any corrections or additional information, especially regarding issues unknown to us.
