Correlation attack — In cryptography, correlation attacks are a class of known plaintext attacks for breaking stream ciphers whose keystream is generated by combining the output of several linear feedback shift registers (called LFSRs for the rest of this article)… … Wikipedia
Timing attack — In cryptography, a timing attack is a side channel attack in which the attacker attempts to compromise a cryptosystem by analyzing the time taken to execute cryptographic algorithms. The attack exploits the fact that every operation in a computer … Wikipedia
Brute-force attack — The EFF s US$250,000 DES cracking machine contained over 1,800 custom chips and could brute force a DES key in a matter of days. The photograph shows a DES Cracker circuit board fitted with 32 Deep Crack chips and some control chips. In… … Wikipedia
Frequency analysis — In cryptanalysis, frequency analysis is the study of the frequency of letters or groups of letters in a ciphertext. The method is used as an aid to breaking classical ciphers.this is wrong is based on the fact that, in any given stretch of… … Wikipedia
Ciphertext indistinguishability — is a property of many encryption schemes. Intuitively, if a cryptosystem possesses the property of indistinguishability, then an adversary will be unable to distinguish pairs of ciphertexts based on the message they encrypt. The property of… … Wikipedia
Autokey cipher — An autokey cipher (also known as the autoclave cipher) is a cipher which incorporates the message (the plaintext) into the key. There are two forms of autokey cipher: key autokey and text autokey ciphers. A key autokey cipher uses previous… … Wikipedia
Cryptanalysis of the Enigma — enabled the western Allies in World War II to read substantial amounts of secret Morse coded radio communications of the Axis powers that had been enciphered using Enigma machines. This yielded military intelligence which, along with that from… … Wikipedia
Bombe — In the history of cryptography, the Bombe was an electromechanical device used by British cryptologists to help break German Enigma machine signals during World War II. The bombe was designed by Alan Turing, with an important refinement suggested … Wikipedia
Password — For other uses, see Password (disambiguation). A password is a secret word or string of characters that is used for authentication, to prove identity or gain access to a resource (example: an access code is a type of password). The password… … Wikipedia
Password cracking — is the process of recovering passwords from data that has been stored in or transmitted by a computer system. A common approach is to repeatedly try guesses for the password. The purpose of password cracking might be to help a user recover a… … Wikipedia
Rabin cryptosystem — The Rabin cryptosystem is an asymmetric cryptographic technique, whose security, like that of RSA, is related to the difficulty of factorization. However the Rabin cryptosystem has the advantage that the problem on which it relies has been proved … Wikipedia
