This paper presents a new proposed fitness function for G.A. Linear Attack & an enhanced technique for G.A. Differential Attack in order to enhance performance of previous G.A. Differential Attacks [1][8].G.A. Linear Attack was implemented on DES-4 Rounds while G.A. Differential Attack was implemented on DES 6-rounds. Both attacks were capable to break DES and extract key bits in less than one second. Experimental results show that G.A. enhanced the overall performance & memory consumption. Therefore G.A. can be used to enhance Differential Attack & Linear Attack for various DES-like cryptosystems.
