Dear Roman Black,+Thank you for putting such interesting and useful electric circuits, and descriptions of how they work, on the web.
I hope you won't be too disappointed when I tell you that The ELK Theory - Unbreakable Encryption is the same as "one-time pad" encryption . Apparently the one-time pad was invented and patented around 1920 .
Rather than use "+" while encrypting and "-" while decrypting, I find it simpler to use the same operator in both directions. (So "double encrypting" with the same keyword gives me the plaintext back -- I don't need a "encrypt/decrypt" switch on the machine). The Beaufort cipher uses "-" in both directions. The original one-time pad used "XOR" in both directions. (Is there any other operator that does not require a "encrypt/decrypt" switch?) -- David Cary (DAV-MP-E62a)
