Module ntru::rand

Rand module

This module includes all the needed structs and functions to interact with the randomness needed by NTRU. Both, key generation and encryption need a source of randomness, for that they need a RandContext, that can be generated from a RandGen. The recommended RNG is the RNG_DEFAULT. If needed, in this module random data can be generated with the generate() function. Also both random TernPoly and ProdPoly can be generated.

Structs

RandContext	A random context for key generation and encryption
RandGen	Random number generator

Constants

RNG_CTR_DRBG	Deterministic RNG based on CTR_DRBG
RNG_DEFAULT	Default RNG
RNG_DEVRANDOM	Unix RNG, /dev/random
RNG_DEVURANDOM	Unix default RNG, /dev/urandom

Functions

generate	Generate random data
init	Initialize a new rand context
init_det	Generate a new deterministic rand context
