Cryptanalyse

Cryptanalysis (from the Greek kryptós, "hidden", and analýein, "to analyze") refers to the process of analyzing information systems in order to understand hidden aspects of the systems. Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, … See more In encryption, confidential information (called the "plaintext") is sent securely to a recipient by the sender first converting it into an unreadable form ("ciphertext") using an encryption algorithm. The ciphertext is sent … See more Cryptanalysis has coevolved together with cryptography, and the contest can be traced through the history of cryptography—new ciphers being designed to replace old broken designs, … See more Asymmetric cryptography (or public-key cryptography) is cryptography that relies on using two (mathematically related) keys; one private, … See more • Black-bag cryptanalysis • Man-in-the-middle attack • Power analysis • Replay attack See more • Boomerang attack • Brute-force attack • Davies' attack See more • Birthday attack • Hash function security summary • Rainbow table See more Quantum computers, which are still in the early phases of research, have potential use in cryptanalysis. For example, Shor's Algorithm could factor large numbers in polynomial time, in effect breaking some commonly used forms of public-key encryption. See more WebCryptanalysis. This section documents the ways in which many cryptographic ciphers can be cryptanalysed and broken. The easiest ciphers to break are the ones which have existed …
