Frequency Analysis: A method used in cryptanalysis to study the frequency of letters or groups of letters in a ciphertext. The technique is based on the fact that, in any given stretch of written language, certain letters and combinations of letters occur with varying frequencies. If an unauthorized entity conducts frequency analysis successfully, it can potentially decrypt and access sensitive information without authorization.
