Hello all
I have some questions about cmpa and elftosb-gui tool
1. what is RKTH input in elftosb-gui->device->security tab? it is the value of ROTKH[...] in CMPA area? And how to write up to 4 ROTKH in CMPA?
2. what if i uncheck "!!Seal security configuration!!" when i process the data?
Best regards
Charles
Hello,
The RKTH is 32 byte SHA-256 hash of SHA-256 hashes of up to four root public keys.Multiple root public keys are supported to allow for key revocation.
You may review the information on chapter 7 of the user manual for the RKTH. Please let me know if you have further qustions.
For the "Seal security configuration" checkbox, I will confirm this information and update you as soon as possible.
Best Regards,
Sabina
