Note 1 =
The key for these commands is input through the PCI bus (data input interface)
Note 2 =
This is a PKCS 12 method for deriving a 3DES key from a password, salt and iteration count.
Note 3 =
The Exponentiation Using CRT and Exponentiation functions are generic math functions; all
parameters are input through the PCI interface (data input interface).
Note 4 =
When operating in the FIPS140-1 mode, it is not possible for secret keys, private keys or critical
security parameters to cross the PCI bus without being wrapped (encrypted) using the Key-Wrapping
Key.
Note 5 =
User Login is the process that takes the board from an unauthenticated state to the authenticated
state. Only one user may be authenticated at a particular time. Consequently, the User Login process
cannot be started from the authenticated state. Nonetheless, the User Login process cannot be
completed successfully without authentication.
Note 6 =
This command is used for generating the key-wrapping-key.
Note 7 =
When the board is in the zeroized state, it is possible to for an unauthenticated user to uninitialize
the board.
Note 8 =
These operations must access stored cryptographic keys. The keys may not be input through the
PCI interface.

10.1 Key Generation
Random number generation for key generation is accomplished using
the algorithm described by appendix C of ANSI standard X9.17. This
algorithm will use a seed value V (from appendix C) that is generated by
the random number generator in the FastMap chip. Using this algorithm
ensures that the keys generated will be consistent with the requirements
of FIPS 140-1. Performing the key generation in this manner will ensure
