Hello,
I am following the CST Code Signing Tool guide paragraph 3.1.2.1 : running the hab4_pki_tree. script to create the Keys efuses bin data.
I don't know what I should answer to the question :
– Do you want the SRK certificates to have the CA Flag set?
– Answer ‘y’ for a standard tree, ‘n’ for fast authentication tree.
Is fast authentication tree supported by iMX8m mini processor ?
Is there a place where they explain what this fast authentication for PKI tree is ?
Can I answer yes even if at the beginning I answered no to the question "Do you want to use an existing CA key ?"
thank you
I think I found explanation here :
https://www.nxp.com/docs/en/application-note/AN4581.pdf at Appendix C.
It is a document not supposed to cover iMX8m mini but I seee it refers anyway to HABv4 so I guess the fast authentication explanation at Appendix C applies anyway.
Hello,
Yes, the fast authentication is described in the Appendix C and i.MX8Mm supports
this feature.
Regards,
Yuri.
