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]
- Cryptology [r]: The theory and practice of protecting the content of communications, and of defeating the protective measures [e]
- Information theory [r]: Theory of the probability of transmission of messages with specified accuracy when the bits of information constituting the messages are subject, with certain probabilities, to transmission failure, distortion, and accidental additions. [e]

Subtopics
- Advanced Encryption Standard [r]: A US government standard issued in 2002 for a stronger block cipher to succeed the earlier Data Encryption Standard. [e]
- Alphabetic substitution [r]: Add brief definition or description
- Authenticator [r]: Add brief definition or description
- Bulk encryption [r]: The encipherment of all traffic on a digital transmission medium, without awareness of multiplexed channels, data link protocols, etc., in the medium. [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]
- 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]
- Cryptanalysis [r]: The sub-field of cryptology which deals with breaking into existing codes and ciphers. [e]
- 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]
- Diffie-Hellman [r]: A technique that allows two parties to safely establish a shared secret for use as a cryptographic key, even if someone is eavesdropping on their interaction. It requires that the parties have some means of authentication to be sure they are talking to the right person. [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]
- Feistel cipher [r]: Add brief definition or description
- William Friedman [r]: Possibly the greatest cryptologist in history, he pioneered the application of mathematics to cryptanalysis and built the U.S. Army Signal Intelligence Service technical base. [e]
