Platform SCP keys

[bboozzoo]

Maybe I missed that in the documentation, but when the SCP keys are rotated using SCPInitializeUpdate as described in GlobalPlatform Technology Secure Channel Protocol '03' Card Specification v2.3 – Amendment D, do the the Platform SCP keys listed in AN12436 for the specific chip become invalid and it is no longer possible to establish SCP using those keys?

Hi @bboozzoo ,

Yes, after rotation, the Platform SCP03 keys used during initial authentication will be replaced with the new keys, but if you save the old keys somewhere, it is also possible to rotate them back.

Have a great day,
Kan
