XOR OTP was known impenetrable since the 40's.
interestingly wikimierda has this bit https://en.wikipedia.org/wiki/One-time_pad
"First described by Frank Miller in 1882,[4][5] the one-time pad was re-invented in 1917. On July 22, 1919, U.S. Patent 1,310,719 was issued to Gilbert Vernam for the XOR operation used for the encryption of a one-time pad"
So...the technique is older than 1940s...
The technique, yes, a general proof of perfect secrecy, no. Up until the proof, at the earliest ca. (Shannon 1949 public, 1945 classified) and (Kotelnikov 1941 classified), all they had was a hunch that something magical was happening... a theory, but did not really know if it was snakeoil or not until then. To the luck of earlier users, it turned out solid, though improper usage still fell to things like VENONA. https://en.wikipedia.org/wiki/Claude_Shannon https://en.wikipedia.org/wiki/Communication_Theory_of_Secrecy_Systems https://www.cs.virginia.edu/~evans/greatworks/shannon1949.pdf https://en.wikipedia.org/wiki/A_Mathematical_Theory_of_Communication 1948 A Mathematical Theory of Cryptography, Memorandum MM 45-110-02, Sept. 1, 1945, Bell Laboratories. https://en.wikipedia.org/wiki/Vladimir_Kotelnikov http://www.turpion.org/php/paper.phtml?journal_id=pu&paper_id=6050 http://www.ufn.ru/ru/articles/2006/7/k/ Sergei N Molotkov (Institute of Solid-State Physics, Russian Academy of Sciences, Chernogolovka, Moscow region, Russian Federation) (22 February 2006).
