On a Linear Cryptanalysis of a Family of Modified DES Ciphers with Even Weight S-Boxes
We investigate the effect of inserting extra linearity in the Data Encryption Standard (DES) through appropriate nonsingular linear encodings of the output of the individual S-boxes. More specifically, we examine the general situation when the output of each S-box of the DESis precoded separately in...
