For example , if a differential of 1 => 1 ( implying a difference in the least significant bit ( LSB ) of the input leads to an output difference in the LSB ) occurs with probability of 4 / 256 ( possible with the non-linear function in the AES cipher for instance ) then for only 4 values ( or 2 pairs ) of inputs is that differential possible .
