Parent topics
- 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]
- Signals intelligence [r]: Add brief definition or description
Subtopics
- 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]
- Cryptanalysis [r]: The sub-field of cryptology which deals with breaking into existing codes and ciphers. [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]
- Random number generator [r]: A member of a sequence of which the successive values cannot be predicted, produced by measurement of physical phenomena, appropriate algorithms, or a combination of the two [e]
- Cryptographic hash [r]: Add brief definition or description
- Code (cryptography) [r]: A means of substituting, for the linguistically meaningful symbols of plaintext composed of words or other symbols meaningful to humans, into inherently meaningless numbers, letters, or words that make no sense to a recipient who is not in possession of a codebook or other means of reversing the substitution of symbols [e]
- Cryptographic key [r]: Value used by a computer together with a complex algorithm to encrypt and decrypt messages. [e]
Famous instances
- Data Encryption Standard [r]: A block cipher specification issued by the U.S. government in 1976, intended for sensitive but unclassified data. It is now obsolescent, succeeded by the Advanced Encryption Standard, but still used in commercial systems. [e]
- Advanced Encryption Standard [r]: A US government standard issued in 2002 for a stronger block cipher to succeed the earlier Data Encryption Standard. [e]
- Enigma machine [r]: The primary high-security cryptographic communications security machine of Nazi Germany. Unknown to the Germans, it had been substantially cryptanalyzed by the British Government Code and Cipher School, with French, Polish, and U.S. help. [e]
- PURPLE machine [r]: Add brief definition or description
Famous cryptologists
The AES competition article has a list of well-known players involved in that.

- Auguste Kerckhoffs [r]: Add brief definition or description
- Alan Turing [r]: British mathematician, code breaker and computer pioneer. [e]
