Parameters
OIDAlgo |
XMSS Algorithm ID. It defines a set of XMSS parameters. See Supported XMSS Algorithms for more information. |
idx |
Index of the XMSS tree leaf. |
r |
Pointer to the XMSS signature randomness variable. |
pOTSSign |
Pointer to the WOTS signature. |
pAuthPath |
Pointer to the XMSS authorization path. |
pState |
Pointer to the XMSS signature state. |
Description
This function sets 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
| |
+---------------------------------+
| |
| authorisation path | h * n bytes
| |
+---------------------------------+
n, len are WOTS+ parameters, h is the XMSS tree height.
