Multiple Differential Distinguisher of SIMECK32/64 Based on Deep Learning

Algorithm 2

Encryption of SIMECK.

	Input:
	K∈{0,1}^mn
	Output: k i, 0  ≤  i ≤ r − 1
(1)	if n = 16 or n = 24 then
(2)	j = 0
(3)	else j = 1
(5)	i = 0
(4)	end if
(6)	for i = 1 to r − 1 do
(7)	ki+3 = ti
(8)	ti+3 = ki ⊕ f (ti) ⊕ C ⊕ (zj)i
(9)	end for
(10)	return k i
