Ah, this time it's really a real fool. I 've always thought that three or three rounds are the same thing. Today, when I look at the difference analysis, I always think that something is wrong, but I don't know, in the evening, we should summarize the study of differential analysis and find the problem.
The three, eight, and 16 rounds of words are often mentioned in the differential analysis. I am still wondering, not to say that the triple DES effici
