Abstract

There is presented the differential cryptanalysis method of attack on data encryption standard (DES) reduced to 9 rounds. More precise estimation than that of Biham and Shamir of the signal to noise (S/N) ratio is obtained. Also, method of using the ratio in calculation of required number of plaintexts is suggested. There are given results (time of performance) and implementation’s issues of practical realisation of this attack.
