|
|
<p>The MCUXpresso SDK provides a peripheral driver for the Secure Non-Volatile Storage (SNVS) module.<br/>
|
|
<br/>
|
|
The SNVS module is designed to safely hold security-related data such as cryptographic key, time counter, monotonic counter, and general purpose security information. The SNVS includes a low power section, namely SNVS_LP, that is battery backed by the SVNS (or VBAT) power domain. This enables it to keep this data valid and continue to increment the time counter when the power goes down in the rest of the SoC. The always-powered-up part of the module is isolated from the rest of the logic to ensure that it does not get corrupted when the SoC is powered down. The SNVS is designed to comply with Digital Rights Management (DRM) and other security application rules and requirements. This trusted hardware provides features that allow the system software designer to ensure that the data kept by the device is certifiable. Specially, it incorporates a security monitor that checks for various security conditions. If a security violation is indicated then it invalidates access to its sensitive data, and the secret data, for instance, Zeroizable Secret Key, is zeroized. the SNVS can be also configured to bypass its security features and protection mechanism. In this case it can be used by systems that do not require security. <br/>
