<h1>Measured Boot<a class="headerlink" href="#measured-boot" title="Permalink to this heading"></a></h1>
|
||
<p>Measures firmware components and records them into a platform storage device such as Trusted Platform Module (TPM) or Intel® Platform Trust Technology (Intel® PTT). The recorded measurement can be compared with a golden value, i.e. the expected unique measurement that was calculated on a known, good system. If the measurement does not match the golden measurement the system integrity is considered compromised.</p>
|
||
<p>The integrity of a remote system can be ascertained by comparing the measurement reported by the system to the golden value.</p>
|
||
<p>SBL implements measured boot and supports both discrete TPM device or Intel® PTT (Platform Trusted Technology).</p>
|
||
<div class="admonition note">

<p class="admonition-title">Note</p>

<p>Measured boot should be enabled in conjunction with verified boot to achieve firmware security.</p>
