Symmetric-key algorithms use a single shared key; keeping data secret requires keeping this key secret. Public-key algorithms use a public key and a private key. The public key is made available to anyone (often by means of a digital certificate). A sender encrypts data with the receiver's public key; only the holder of the private key can ...
A key generator [1] [2] [3] is a protocol or algorithm that is used in many cryptographic protocols to generate a sequence with many pseudo-random characteristics. This sequence is used as an encryption key at one end of communication, and as a decryption key at the other.
In 2009, a new related-key attack was discovered that exploits the simplicity of AES's key schedule and has a complexity of 2 119. In December 2009 it was improved to 2 99.5 . [ 2 ] This is a follow-up to an attack discovered earlier in 2009 by Alex Biryukov , Dmitry Khovratovich , and Ivica Nikolić, with a complexity of 2 96 for one out of ...
Hi/Lo is an algorithm and a key generation strategy used for generating unique keys for use in a database as a primary key.It uses a sequence-based hi-lo pattern to generate values.
If the equipment used in quantum key distribution can be tampered with, it could be made to generate keys that were not secure using a random number generator attack. Another common class of attacks is the Trojan horse attack [74] which does not require physical access to the endpoints: rather than attempt to read Alice and Bob's single photons ...

In cryptanalysis, Kasiski examination (also known as Kasiski's test or Kasiski's method) is a method of attacking polyalphabetic substitution ciphers, such as the Vigenère cipher. [ 1 ] [ 2 ] It was first published by Friedrich Kasiski in 1863, [ 3 ] but seems to have been independently discovered by Charles Babbage as early as 1846.
