LMS

Functions such as LMS signature verification and special functions like getters and setters that are required to call algorithms have been implemented.

Example

#define IPPCP_PREVIEW_LMS
#include "ippcp.h"
...

IppsLMSAlgoType alg_id;
alg_id.prmLmotsAlg = IppsLMOTSAlgo::LMOTS_SHA256_N32_W8;
alg_id.prmLmsAlg = IppsLMSAlgo::LMS_SHA256_M24_H10;

status = ippsLMSBufferGetSize(&buffSize, sizeof(msg), alg_id);

status = ippsLMSPublicKeyStateGetSize(&ippcpPubKeySize, alg_id);

status = ippsLMSSignatureStateGetSize(&sigBuffSize, alg_id);

status = ippsLMSSetPublicKeyState(alg_id, pI, pK, pPubKey);

status = ippsLMSSetSignatureState(alg_id, q, pC, pY, pAuthPath, pSignature);

int is_valid=0;
status = ippsLMSVerify(msg, sizeof(msg), pSignature, &is_valid, pPubKey, pScratchBuffer);
