In this paper, firstly, we study the bit transform characteristics of some MDS matrices, and get the result that the bit parity of output is equal to that of input, then we prove the result. Secondly, we give the formula of computing the number of the MDS matrix, and prove the formula simultaneously. The experimental results accord well with the theoretical inference results.
