ptsc Command
Purpose
Collects information from a trusted platform module (TPM) in preparation for an attestation request from an openpts verifier.
Syntax
Description
The ptsc command is the openpts collector. The command is used to gather measurements and events from the TPM (through the tscd interface), construct reference manifests (RMs) and convey them when requested to the openpts verifier. When a system is first configured for trusted boot, the collector must be initialized by using the -i option. This option generates a UUID and an associated RM stored in the /var/ptsc/<UUID>/rm0.xml file. If the system is changed and a new RM is required, the -u option is used and the verifier must be reinitialized.
