Hello,

Hope you are doing well. The main purpose of these APIs is to provide access to functions used and implemented in ROM to authenticate the application image and processing sb3 files.

For this, it is recommended to some of these resources:

KW45 Secure Boot Using the SEC Tool
Programming the KW45 flash for Application and Radio firmware via Serial Wire Debug during
Managing Lifecycles on KW45
Updating KW45 Radio Firmware via ISP using SPSDK
Secure Boot for KW45

So, depending on what you are trying to do, I would recommend you check any of these Application Notes.

Hope this helps.

Best Regards,

Ricardo
