Module ntru::rand

Rand module

This module includes all the needed structs and functions to interact with the randomness needed by NTRUEncrypt. Both, key generation and encryption need a source of randomness, for that they need a NtruRandContext, that can be generated from a NtruRandGen. The recommended RNG is the NTRU_RNG_DEFAULT. If needed, in this module random data can be generated with the generate() function. Also both random NtruTernPoly and NtruProdPoly can be generated.

Structs

NtruRandContext	A random context for key generation and encryption
NtruRandGen

Constants

NTRU_RNG_DEFAULT	default RNG (/dev/urandom on *nix)
NTRU_RNG_DEVRANDOM	Unix RNG, /dev/random
NTRU_RNG_DEVURANDOM	Unix default RNG, /dev/urandom
NTRU_RNG_IGF2	Deterministic RNG based on IGF-2

Functions

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