That explains everything. The next problem is TrouSerS's LoadKeyByUUID function does not support auth secret. The quick workaround is OpenPTS uses LoadKeyByBlob in place of LoadKeyByUUID for this TPM. So the key blob will be stored in some place. e.g. /var/lib/openpts/key.blob And the key auth type and storage location will be configured by /etc/ptsc.conf. regards, -- Seiji
