Differential cryptanalysis

Updated: 10/04/2017 by Computer Hope

Differential cryptanalysis is a branch of study in cryptography that compares the way differences in input relate to the differences in encrypted output. It is used primarily in the study of block ciphers to determine if changes in plaintext result in any non-random results in the encrypted ciphertext. This process is important because when changes in the ciphertext are found to be non-random, it may signify a weakness in the encryption scheme. An unauthorized third party may be able to gain information about what was encrypted, or how it was encrypted by monitoring how the encrypted data has changed.
