Diana cryptosystem cipher
WebDiana is an encryption algorithm similar to the Vigenere and Beaufort algorithms. The type of encryption depends on the crypto key and how it is used. If you use a key word that is … WebThere is only one perfectly secure cryptosystem known Of all the methods of encryption ever devised, only one has been mathematically proved to be completely secure. It is called the Vernam cipher or one-time pad. The worth of all other ciphers is based on computational security.

WebThe ideal cipher model describes a keyed permutation that approximates a random oracle, but with a fixed input size. An ideal cipher with a block size B -bits and key size N -bits should exhibit the following properties: Given any single key K, the distribution of ciphertexts for all 2 B plaintexts is statistically random WebAn authentic reproduction of the cipher used by US Army Special Forces (Green Berets) during the Vietnam War and throughout the cold war period. Designed in conjunction with a Special Forces soldier that actually used …
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. In some hypothetical espionage situations, the one-time pad might be … See more http://pro-technix.com/information/crypto/pages/vernam_base.html
