Matrix multiplication inverse
I am trying to put together an encryption alogritm but i have stuck in the following problem and i don't even know is it supposed to be like this or not!

the problem:

I have 16 byte matrix to be multiplied by [16,16] matrix, and the result is a 16 byte matrix.

Then I should Multiply the result Matrix by the inverse, here i suppose i should get the original 16 byte matrix (according to the algorithm data sheet).

so can you please help me by telling me how can i get back the orginal matrix?

thanks for you help in advance.

regards,
