MSPM0L1306: time required for secure boot

Wilson Liang2
Intellectual 420 points
Part Number: MSPM0L1306

Tool/software:

Hi Sir

For the time required for secure boot of MSPM0L1306.
I actually measured LA as 2 sec (refer to the attachment)
Is there any other shorter asymmetric secure boot? (1306 does not support symmetric secure boot)

In addition, questions about public key and private key
Because TI SDK can be obtained by registering an account
How safe is such a secure boot?
How to customize your own public & private key?

Extended question:

Do you have any suggestions for a comprehensive solution of BSL + secure boot?

thanks.

    Hi Wilson, 

    Yes, it will to take about 2 sec to do the security boot. And there is no other demos so far. It is totally open source and customer can add some control logic to skip some verification at some conditions to fast boot it.

    Due to the private key is different and it just been known by the code author so it is secure the customer's application. We do have provide some tools to generate it please refer to our SDK's document section 3.1 Creating and Using Keys....\mspm0_sdk_2_02_00_05\docs\english\middleware\boot_manager\Secure_Booting_Users_Guide.html

    There is no demo that include seure boot + bsl now, we just have separate demos for that.
