Originality Signature Generation ALgorythm

Hi,

I'm investigating the Originality Signature of SLIX2.

Which data should be encrypted with NXP's private key to obtain the originality signature?

How is signature verification performed?

For Signature Verification, which needs the following inputs:

1) Public Key, that is saved in the dedicated file. As long as you sign an NDA with NXP, you can get it.

2) Signature and UID, two are unique to NXP products. They are stored in a hidden area of the chip and can only be read through dedicated commands.

3) Algorithm, ICODE used is ECDSA, which is an open-source algorithm. The source code can be downloaded on GitHub.

Hope them helps.
