Function Documentation

int get_rnd_int

(

void

)

Get a random integer from /dev/random.

Returns:

random integer

Definition at line 42 of file ntru_rnd.c.

int get_urnd_int

(

void

)

Get a pseudo random integer from /dev/urandom.

Returns:

pseudo-random integer.

Definition at line 66 of file ntru_rnd.c.

void ntru_get_rnd_tern_poly_num	(	fmpz_poly_t	poly,
		const ntru_params *	params,
		uint32_t	num_ones,
		uint32_t	num_neg_ones,
		int(*)(void)	rnd_int
	)

Get a random ternary polynomial with specified numbers of 1 coefficients and -1 coefficients.

Parameters:

poly	the resulting random polynomial [out]
params	the NTRU context
num_ones	the number of 1 coefficients
num_neg_ones	the number of -1 coefficients
rnd_int	function callback which should return a random integer
