+|tcm| supports the integrity check mechanism.
+The integrity check mechanism in TCM verifies the digital signature of centralized configuration files.
+It ensures that TCM only applies configurations that are signed with a trusted private key.
+
+This mechanism allows TCM to:
+
+* Allows updating the configuration with integrity check support.
+* Detect unauthorized changes in centralized configuration.
