About article:

In this paper we study two-round key-alternating block ciphers with round function $f(x)=x^{(2^t+1)2^s},$ where $t,s$ are positive integers. An algorithm to compute the distribution weight in respect to input and output masks is described. Also, in the case $t=1$ the correlation distributions depending on input and output masks are completely determined for arbitrary pairs of masks.
