Description
This function initializes the XMSS signature state. The scheme of the signature is shown below:
+---------------------------------+
| |
| index idx_sig | 4 bytes
| |
+---------------------------------+
| |
| randomness r | n bytes
| |
+---------------------------------+
| |
| WOTS+ signature sig_ots | len * n bytes
| |
+---------------------------------+
| |
| authorization path | h * n bytes
| |
+---------------------------------+
n, len are WOTS+ parameters, h is the XMSS tree height.
