Equivalent Linear Transformation in the AES S Box
Pla Information · Computer Engineering and Applications Journal · 2005
In this paper, an efficient method is proposed which searching the equivalent linear transformation matrix in the AES s box. And the only property that the equivalent linear transformation has the same difference sum distribution is needed. Then it presents an efficient method which determining the correct matrix with the possible value of the combination of the column, the way is more efficient than Fuller and Millan's.
