3.2.2 Monotonic Counter
SHA106 supports one nonvolatile monotonic counter that can count to a value of 10,000.
The counters can be used in one of two
methods :
- Cryptographic Counters:
In this mode, the value of the counter can be read or incremented. It is the responsibility of the host to determine how this counter is used.
- Limited Key Use:
The monotonic counter can be attached to the Symmetric Key stored in Slot 3 to restrict the number of times this key can be used.
