Detailed Description

public API, random polynomials

This file holds the public API of generating random ternary polynomials of the pqc NTRU implementation and is meant to be installed on the client system.

Definition in file rnd.h.

Function Documentation

int get_rnd_int

(

void

)

Get a random integer from /dev/random.

Returns

random integer

int get_urnd_int

(

void

)

Get a pseudo random integer from /dev/urandom.

Returns

pseudo-random integer.

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
