Set LMS Signature State
Syntax
IppStatus ippsLMSSetSignatureState (const IppsLMSAlgoType OIDAlgo, Ipp32u q, const Ipp8u* pC, const Ipp8u* pY, const Ipp8u* pAuthPath, IppsLMSSignatureState* pState);
Include Files
ippcp.h
Parameters
OIDAlgo |
LMS Algorithm ID. It defines a set of LMS parameters. See Supported LMS Algorithms for more information. |
q |
Index of the LMS tree leaf. |
pC |
Pointer to the random string C. |
pY |
Pointer to Y that is a part of the LM-OTS string. |
pAuthPath |
Pointer to the LMS authorization path. |
pState |
Pointer to the LMS signature state. |
Description
This function sets the LMS signature state. The scheme of the signature is shown below:
+---------------------------------+ | q | 4 bytes +---------------------------------+ | LM-OTS signature | 4 + n * (p + 1) bytes +---------------------------------+ | IppsLMSAlgo | 4 bytes +---------------------------------+ | authorisation path | h * m bytes +---------------------------------+
m, h are LMS parameters.
The scheme of the LM-OTS signature is shown below:
+---------------------------------+ | IppsLMOTSAlgo | 4 bytes +---------------------------------+ | C | n bytes +---------------------------------+ | Y | p * n bytes +---------------------------------+
n, p are LM-OTS parameters.
Important
This is a Preview Feature. You need to enable the IPPCP_PREVIEW_LMS macro to use the feature.Return Values
ippStsNoErr |
Indicates no error. All single operations executed without errors. Any other value indicates an error or warning. |
ippStsNullPtrErr |
Any of the input parameters is a NULL pointer. |
ippStsBadArgErr |
OIDAlgo.lmotsOIDAlgo < the minimum value for IppsLMOTSAlgo, OIDAlgo.lmotsOIDAlgo > the maximum value for IppsLMOTSAlgo, OIDAlgo.prmLmsAlg < the minimum value for IppsLMSAlgo, OIDAlgo.prmLmsAlg > the maximum value for IppsLMSAlgo or q is incorrect. |
