5.1.4 Nonce Command

The Nonce command generates a nonce (number used once) for use by a subsequent command by combining a random number (which can be generated internally or externally) with an input value from the system. The resulting nonce is stored internally in three possible buffers: TempKey, Message Digest Buffer and Alternate Key Buffer. Instead of generating a nonce, a value may be passed to the device if so desired.
