Limitation and prerequisites

These invalidation keys are effective only if unlock keys are aligned at 128 bits, otherwise
the ECC must be computed explicitly for given data.

The user adopts the invalidation keys only in case valid unlock keys are saved in UTest and
a new configuration is applied.

Invalidation keys must be written at exact positions of unlock keys which means overwrite
the unlock keys.
