The classical one-time pad of espionage used actual pads of minuscule, easily concealed paper, a sharp pencil, and some mental arithmetic. The method can be implemented now as a software program, using data files as input (plaintext), output (ciphertext) and key material (the required random sequence). See more In cryptography, the one-time pad (OTP) is an encryption technique that cannot be cracked, but requires the use of a single-use pre-shared key that is not smaller than the message being sent. In this technique, a See more Frank Miller in 1882 was the first to describe the one-time pad system for securing telegraphy. The next one-time pad system was electrical. In 1917, Gilbert Vernam (of AT&T Corporation) invented and later patented in 1919 ( See more Despite Shannon's proof of its security, the one-time pad has serious drawbacks in practice because it requires: • Truly random, as opposed to pseudorandom, one-time pad values, which is a non-trivial requirement.

Assume two pads of paper containing identical random sequences of letters were somehow previously produced and securely … See more One-time pads are "information-theoretically secure" in that the encrypted message (i.e., the ciphertext) provides no information about the original message to a cryptanalyst (except the maximum possible length of the message). This is a very strong notion … See more Applicability Despite its problems, the one-time-pad retains some practical interest.
