The server includes a Trusted Platform Module (TPM) as part of the SP. TPM refers to the hardware component and software that provides protected key storage and reliable measurements of software used to boot the operating system.
Oracle Solaris uses TPM to securely store encryption keys. TPM, together with the other measures that are described in the Oracle Solaris documentation, secures the system from unauthorized access by users of applications.
The platform owner must initialize TPM by setting an owner password that is used to authorize privileged operations. The platform owner, also called the TPM owner, differs from the traditional superuser.
