Hi Raveendranath,
This isn't ownerid, this is eownerID for MULTIPLE_OWNER scenario.
Best regards,

Title : [dev] SaveOwnerPSK - Bug or Intentional
Hi,
While reading through the ownership transfer code, I came across this SaveOwnerPSK function.
This was generating a Symmetric pair wise key. The ownerid of the credential is set NULL, meaning that rowneruuid is all zeros. Is this intentional or a bug?
802 static OCStackResult SaveOwnerPSK(OCProvisionDev_t *selectedDeviceInfo)
803 {
804 OIC_LOG(DEBUG, TAG, "IN SaveOwnerPSK");
806 OCStackResult res = OC_STACK_ERROR;
808 CAEndpoint_t endpoint;
809 CopyDevAddrToEndpoint(&selectedDeviceInfo->endpoint, &endpoint);
810 endpoint.port = getSecurePort(selectedDeviceInfo);
812 OicUuid_t ownerDeviceID = {.id={0}};
813 if (OC_STACK_OK != GetDoxmDeviceID(&ownerDeviceID))
814 {
815 OIC_LOG(ERROR, TAG, "Error while retrieving Owner's device ID");
816 return res;
817 }
819 OicSecKey_t ownerKey;
820 memset(&ownerKey, 0, sizeof(ownerKey));
822 uint8_t ownerPSK[OWNER_PSK_LENGTH_128] = { 0 };
823 ownerKey.data = ownerPSK;
824 ownerKey.len = OWNER_PSK_LENGTH_128;
825 ownerKey.encoding = OIC_ENCODING_RAW;
827 //Generating OwnerPSK
828 CAResult_t pskRet = CAGenerateOwnerPSK(&endpoint,
829 (uint8_t *)GetOxmString(selectedDeviceInfo->doxm->oxmSel),
830 strlen(GetOxmString(selectedDeviceInfo->doxm->oxmSel)),
831 ownerDeviceID.id, sizeof(ownerDeviceID.id),
832 selectedDeviceInfo->doxm->deviceID.id, sizeof(selectedDeviceInfo->doxm->deviceID.id),
833 ownerPSK, OWNER_PSK_LENGTH_128);
835 if (CA_STATUS_OK == pskRet)
836 {
837 OIC_LOG(DEBUG, TAG,"Owner PSK dump:\n");
838 OIC_LOG_BUFFER(DEBUG, TAG,ownerPSK, OWNER_PSK_LENGTH_128);
839 //Generating new credential for provisioning tool
840 OicSecCred_t *cred = GenerateCredential(&selectedDeviceInfo->doxm->deviceID,
841 SYMMETRIC_PAIR_WISE_KEY, NULL,
842 &ownerKey, NULL);
