cryptanalysis

Abbreviation(s) and Synonym(s):

CA

Definition(s):

  Operations performed in defeating cryptographic protection without an initial knowledge of the key employed in providing the protection.

  1. Operations performed to defeat 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 in the algorithm itself.
