Information Theory - Applications To Other Fields - Intelligence Uses and Secrecy Applications
... can break systems based on asymmetric key algorithms or on most commonly used methods of symmetric key algorithms (sometimes called secret key algorithms), such as block ciphers ... information between the plaintext and ciphertext (conditioned on the key) can ensure proper transmission, while the unconditional mutual information between the plaintext and ciphertext remains zero, resulting in ... of the ciphertext but not of the key ...
History Of Cryptography - Modern Cryptography - Public Key
... new method of distributing cryptographic keys, which went far toward solving one of the fundamental problems of cryptography, key distribution, and has become ... also stimulated the almost immediate public development of a new class of enciphering algorithms, the asymmetric key algorithms ... Prior to that time, all useful modern encryption algorithms had been symmetric key algorithms, in which the same cryptographic key is used with the underlying algorithm by ...
Public-key Cryptography - Practical Considerations - Weaknesses
... Among symmetric key encryption algorithms, only the one-time pad can be proven to be secure against any adversary - no matter how much computing power is available ... However, there is no public-key scheme with this property, since all public-key schemes are susceptible to a "brute-force key search attack" ... the work factor can be increased by simply choosing a longer key ...

Famous quotes containing the word key:

    Power, in Case’s world, meant corporate power. The zaibatsus, the multinationals ..., had ... attained a kind of immortality. You couldn’t kill a zaibatsu by assassinating a dozen key executives; there were others waiting to step up the ladder; assume the vacated position, access the vast banks of corporate memory.
