- See also changes related to Cryptology, or pages that link to Cryptology or to this page or whose text contains "Cryptology".
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]: the practice of acquiring information through monitoring the electromagnetic signals deliberately trasmitted by an opponent, including communications (COMINT) and non-communications electronics such as radar (ELINT). [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]
- 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 [r]: Add brief definition or description
- Cryptanalysis [r]: The sub-field of cryptology which deals with breaking into existing codes and ciphers. [e]
- 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]
- Cryptographic key [r]: Value used by a computer together with a complex algorithm to encrypt and decrypt messages. [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]
- 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.
- 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]
- Auguste Kerckhoffs [r]: A 19th Century French writer, famous for giving some axioms for cryptography. [e]
- Alan Turing [r]: British mathematician, code breaker and computer pioneer. [e]
- Claude Shannon [r]: (1916-2001) American theoretical mathematician, founder of information theory. [e]
- Sir Francis Walsingham [r]: Add brief definition or description
Government cryptology
- Communications intelligence [r]: The subset of SIGINT concerned with signals intended to be intelligible to human beings, in the form of voice, messages, or images. [e]
- Communications Security Establishment [r]: The Canadian government organization responsible for communications security and signals intelligence [e]
- Government Communications Headquarters [r]: The British government agency responsible for signals intelligence and information assurance [e]
- Government Communications Security Bureau [r]: The organization, in the government of New Zealand, which has responsibility for information security and signals intelligence [e]
- National Security Agency [r]: An organization within the United States Department of Defense, with the dual roles of the principal signals intelligence agency in the United States intelligence community, but also having the responsibility for information assurance of military, diplomatic, and other critical communications. [e]
- Signals intelligence [r]: the practice of acquiring information through monitoring the electromagnetic signals deliberately trasmitted by an opponent, including communications (COMINT) and non-communications electronics such as radar (ELINT). [e]
