| Abstract : | This paper describes an investigation of a potential weakness in DES which leads to a statistical property observable in plaintextciphertext pairs and dependent on the key. However, the number of encryptions of known plaintext needed to exploit this property is comparable to the number of encryptions of an exhaustive key search, so the \weakness " is mainly of theoretical interest., |
