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. Random number generation in … See more • Agrippa (A Book of the Dead) • Information theoretic security • Numbers station See more Suppose Alice wishes to send the message hello to Bob. 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. In some hypothetical espionage situations, the one-time pad might be … See more http://pro-technix.com/information/crypto/pages/vernam_base.html WebAlberti Cipher Disk - powerful encryption from 15th century The Alberti Cipher Disk is the first example of a true "polyalphabetic" cipher device using two dissimilar alphabets. ... $28.00 Diana Cryptosystem US Army Special Forces Cipher Disk.
