Function Documentation

double adp_lrot	(	WORD_T	da,
		WORD_T	db,
		int	r
	)

The ADD differential probability of (left) rotation (LROT):

double adp_lrot2_exper	(	const WORD_T	da,
		const WORD_T	db_r,
		const WORD_T	db_s,
		const int	r,
		const int	s
	)

The ADD differential probability of one input a left rotated by two constants in parallel: b1 = a <<< r, b2 = a <<< s .

double adp_lrot_exper	(	const WORD_T	da,
		const WORD_T	db,
		const int	r
	)

The ADD differential probability of (left) rotation (LROT): computed experimentally over all inputs.

void adp_lrot_odiffs	(	const WORD_T	da,
		const int	r,
		WORD_T	dx[4],
		double	P[4]
	)

For given input difference da, generate all four possible output ADD differences after left rotation together with their probabilities.
