A set of practical examples is proposed to get an overview and to understand the STM32H5 security solutions.
These practical examples are based on the boards, tools and code examples provided by ST.
For the examples listed below, each step to be followed is described in detail.
It is advised to start with these examples before making your own trials or using other security related examples available in the STM32Cube_H5.

1. Secure Boot
The secure boot and related root of trust is implicitly used in all the proposed " How to start" step by step examples.
A bootpath can be defined from scratch and a related firmware frame is generated using the STM32CubeMx.
The example on this topic is based on the STM32CubeMx.
- The Secure Boot for STM32H5 wiki article explains the possible bootpaths for the different STM32H5 series.
- The Secure Boot STM32H5 How to Introduction wiki article gives a short technical introduction to be read before executing the getting started.
2. Debug Authentication
It is key to well understand how to set the Debug Authentication (DA) in order to define the appropriate rights to reopen the debugger once closed.
- It is strongly advised to read the Debug Authentication for STM32H5 wiki article.
- The Debug Authentication STM32H5 How to Introduction wiki article summarizes all the technical know-how to be read before executing the getting started.
- Two getting started dedicated to the DA are proposed, using for the user application firmware the GPIO_IOToggle of the STM32CubeH5.
- Two further getting started examples address the Debug Authentication, including a step-by-step section showing the principle of the certificate chain, and how to use it. But it needs to execute the related step-by-step starting from the beginning.

- Part of the OEMiROT how to start: How to start with OEM-iROT on STM32H573 and 563
3. OEMiROT
An OEM can develop its own customized Immutable Root Of Trust (OEMiROT).
It is advised to read the Secure Boot for STM32H5 wiki article to understand the different possible Root of Trust.
- The OEMiROT STM32H5 How to Introduction wiki article gives a short technical introduction to be read before executing the getting started.
- Two getting started dedicated to the OEMiROT based on the STM32CubeH5 are proposed:
4. STiROT
An immutable root of trust defined by ST is included natively for the STM32H57x series.
It is an embedded firmware stored in the system flash and that cannot be modified.
It is advised to read the Secure Boot for STM32H5 wiki article to understand the different possible Root of Trust.
- The STiROT STM32H5 How to intro wiki article gives a short technical introduction to be read before executing the getting started.
- The How to start with ST-iROT on STM32H573 article provides an example based on the STM32CubeH5.
5. Secure Manager
ST provides a solution enhancing the security offer and this solution is easy to install and to use.
This solution is called the Secure Manager. It provides a secure boot, updatable root of trust, PSA secure services available at run time of the application, and a secure module management.
The secure manager is only supported for the STM32H573xx product line.
- The Secure Manager wiki article gives technical explanations
- The Secure Manager STM32H5 How to Intro wiki article is an introduction for the "step by step".
- The How to start with Secure Manager on STM32H573 wiki article describes, step by step, how to install and use the Secure Manager.
