In this paper, we propose an expanded set of design criteria for the generation of DES-like S-boxes which enable DES being immunized against three known robust cryptanalysis, i.e., diierential, Improved Davies' and linear cryptanalysis and we also suggest a set of new 8 DES-like S-boxes generated by our proposed design criteria in order to replace with the(More)
In this paper, we discuss uniied conditions which enable DES being immunized against two known robust attacks, i.e., diierential and linear cryptanalysis and we also suggest a set of new 8 DES-like S-boxes generated by our new design conditions in order to replace with the current DES S-boxe. This leads us to conclude that DES can survive from two powerful(More)
