+The Mbed implementation of the Platform Security Architecture (PSA) provides root of trust services and infrastructure for developing IoT applications.
 
-When Mbed OS is running on a PSA Security Model compliant target, the Mbed implementation of PSA helps to protect cryptographic assets, credentials and critical code sections by providing an isolation between a [Secure Processing Environment (SPE)](../introduction/glossary.html) and a [Non-Secure Processing Environment (NSPE)](../introduction/glossary.html). The [Secure Partition Manager (SPM)](../introduction/glossary.html), which uses the target's hardware features, manages the isolation. The SPM provides standardized [IPC](../introduction/glossary.html) APIs that you can use regardless of system architecture (v8M, TEE on Cortex-A) or inside another chip.
