http://williamstallings.com/Extras/Security-Notes/lectures/blockB.html Weborder to avoid some variant forms of differential cryptanalysis, permu tation P needs to be chosen to prevent easy propagation of a constant XOR value back into the same S-box. We redesign the LOKI cipher to form LOKI91, to illustrate these results, as well as to correct the key schedule to remove the formation of equivalent keys. We conclude
