I was recentely asked in the comments on some details on tamper-proofing of a smartcard in question. The term "FIPS-201" was used to specify what kind of details was needed.
I understand that FIPS 140-2 defines four levels of hardware (/software) security for smartcards / software / HSMs for these devices to protect, use and manage keys.
When "asked" for FIPS-201, Wikipedia says that this is a set of requirements for personal identity validation (PIV). So a piece of soft-/ hardware can either be FIPS-201 compliant or not.
But none of the pages stated what those requirements actually are, hence my question:
What are the central requirements for PIV as per FIPS-201?
