Parent topics
- Cryptography [r]: A field at the intersection of mathematics and computer science that is concerned with the security of information, typically the confidentiality, integrity and authenticity of some message. [e]
- Information security [r]: The set of policies and protective measures used to ensure appropriate confidentiality, integrity and availability to information; usually assumed to be information in a computer or telecommunications network but the principles extend to people and the physical world [e]
- Cipher [r]: A means of combining plaintext (of letters or numbers, or bits), using an algorithm that mathematically manipulates the individual elements of plaintext, into ciphertext, a form unintelligible to any recipient that does not know both the algorithm and a randomizing factor called a cryptographic key [e]
Subtopics
See our table of block ciphers for links to individual ciphers.
- Avalanche (cryptography) [r]: A desirable property for operations in a cipher or hash, where a small change (even a single bit) quickly builds up to creating large effects. [e]
- Round (cryptography) [r]: A relatively simple operation which, when repeated many times, can be used to build an iterated cipher or hash. [e]
- S-box (cryptography) [r]: A substitution box or lookup table. [e]
- Cryptanalysis [r]: The sub-field of cryptology which deals with breaking into existing codes and ciphers. [e]
- Block cipher modes of operation [r]: Methods of combining multiple block cipher operations to achieve a larger goal. [e]
- Hash (cryptography) [r]: An algorithm that produces a fixed-size digest from an input of essentially arbitrary size. [e]
- Key (cryptography) [r]: Characteristics and generation of data which, in combination with a cryptographic algorithm, introduces or removes the concealment applied to plaintext or taken to ciphertext; key management is arelated but separate discipline of secure distribution of keys and entering them into cryptosystems [e]
- Key management (cryptography) [r]: Add brief definition or description
- Stream cipher [r]: A cipher that encrypts data by mixing it with the output of a pseudorandom number generator controlled by a key; to decrypt, run the same generator with the same key to get the same pseudorandom data, then reverse the mixing step. [e]
- Permutation cipher [r]: Add brief definition or description
- Transposition cipher [r]: Add brief definition or description
- Code book attack [r]: Attacking a block cipher by creating a code book, collecting plaintext/ciphertext pairs. [e]
- AES competition [r]: A competition run by the US National Institute of Standards and Technology to chose a block cipher to become the Advanced Encryption Standard. [e]
