Specified by:

generateKeyPair in interface AsymmetricCipherKeyPairGenerator

Returns:

a key pair

generateKeyPairSingleThread

public AsymmetricCipherKeyPair generateKeyPairSingleThread()

Generates a new signature key pair. Runs in a single thread.

Returns:

a key pair

generateBoundedBasis

public NTRUSigningPrivateKeyParameters.Basis generateBoundedBasis()

Creates a basis such that |F| < keyNormBound and |G| < keyNormBound

Returns:

a NTRUSigner basis
