Constructor Detail

LMOTSParameterSpec

public LMOTSParameterSpec(int keysize)

(EXAMPLE/TEST ONLY) Constructs an example Parameter spec using the bit length of the Encryption Key. This should be understood as a test or example parameter spec and not necessary one that is applicable for actual use.

Parameters:

keysize - the bit length of the key used for encrypting the message

LMOTSParameterSpec

public LMOTSParameterSpec(int[] f,
                          int phi)

Construct new LMOTS parameters from the given parameters.

Parameters:

f - irreducible polynomial specified on page 10 in the paper

phi - this parameter depends on f and is described on page 7 in the paper
