Monotonic Counter Objects

Monotonic counter objects represent hardware counters that exist on the device. The counter is guaranteed to increase each time its value is read, but not necessarily by one.

Table 18, Monotonic Counter Attributes
Attribute Data Type Meaning
CKA_RESET_ON_INIT1 CK_BBOOL The value of the counter will reset to a previously returned value if the token is initialized using C_InitializeToken.
CKA_HAS_RESET1 CK_BBOOL The value of the counter has been reset at least once at some point in time.
CKA_VALUE1 Byte Array The current version of the monotonic counter. The value is returned in big endian order.

1Read Only

The CKA_VALUE attribute may not be set by the client.
