Hi all,

I want to secure the RootCA/Keys from being tampered with or altered on the device.

How to do a Proof of Concept for the same, proving RootCA/Keys generated by TPM9672 cannot be tampered?

TPM9672 can wrap keys and password-protected "tpm2tss-genkey -a rsa -s 2048 ./tpm2/tpm_wrapped_keys/client. Key -p passw0rd" but is not able to conclude POC.


Thank You!

Hi @snehapra

Thank you for the information provided. It's really helpful.
I'm working on it. The Root of Trust for Storage can fulfill the requirements for Proof of Concept. 
I will let you know if any further information is needed.

Hi @Dev_2048,

OPTIGA TPMs are TCG compliant and the hardware and firmware are evaluated by CC (Common Criteria) and FIPS. According to TCG Protection Profile, TPM 2.0 products demonstrate FIPS 140-2 Level 2 and EAL4+ CC certification making it tamper-resistant.
