"Communication Theory of Secrecy Systems" is a paper published in 1949 by Claude Shannon discussing cryptography from the viewpoint of information theory.[1] It is one of the foundational treatments (arguably the foundational treatment) of modern cryptography.[2] His work has been described as a "turning point, and marked the closure of classical cryptography and the beginning of modern cryptography."[3] It has also been described as turning cryptography from an "art to a science".[4] It is also a proof that all theoretically unbreakable ciphers must have the same requirements as the one-time pad.

The paper serves as the foundation of secret-key cryptography, including the work of Horst Feistel, the Data Encryption Standard (DES), Advanced Encryption Standard (AES), and more.[5]

Shannon published an earlier version of this research in the formerly classified report A Mathematical Theory of Cryptography, Memorandum MM 45-110-02, Sept. 1, 1945, Bell Laboratories.[6] [7] This report also precedes the publication of his "A Mathematical Theory of Communication", which appeared in 1948.
