1. :: Real one time pads have historically been drawn by hand using lottery machines. 2. :Probably what the OP's professor is talking about is a one time pad system. 3. I've long understood that One Time Pad ciphers are theoretically unbreakable-this makes sense to me. 4. He creates a message using an Error-correcting code and puts it through your biased one time pad . 5. They are always encrypted, frequently by unbreakable one time pad ciphers using key material distributed using diplomatic couriers. 6. During the summer of 1945, a Soviet cipher clerk had reused a one time pad to transmit intelligence traffic. 7. This led to the development of electromechanical devices as cipher machines, and to the only unbreakable cipher, the one time pad . 8.

So how do you get the answer to be " yes, it will be random ", the same as xoring by a random one time pad ? 10. If you Google for " one time pad software ", you can find programs that use the technique . talk ) 17 : 51, 20 August 2013 ( UTC)
