Cryptanalysis – 1)

Primary definition

Operations performed in defeating cryptographic protection without an initial knowledge of the key employed in providing the protection. 2) The study of mathematical techniques for attempting to defeat cryptographic techniques and information system security. This includes the process of looking for errors or weaknesses in the implementation of an algorithm or of the algorithm itself. (SP 800-57 Part 1; CNSSI-4009) (NISTIR) The operations performed in defeating or circumventing cryptographic protection of information by applying mathematical techniques and without an initial knowledge of the key employed in providing the protection. (Adapted from: CNSSI 4009, NIST SP 800-130) (NICCS) Extended Definition: The study of mathematical techniques for attempting to defeat or circumvent cryptographic techniques and/or information systems security.
