Patent ID: 8423792

Claim:
An apparatus comprising: at least one driver of an automated tape library, the at least one drive communicating an encryption key request as serial data with a size smaller than a maximum size; an encryption module that provides encryption data and communicates using encryption messages comprising encryption keys no smaller than the maximum size; and a communication module that converts the encryption key request serial data from 16-bit data to 32-bit data, combines the serial data from the at least one driver into a driver message of at least the maximum size with a wrapper providing information about driver encryption message and a destination for the driver, relays the driver message to the encryption module, divides an encryption message from the encryption module comprising a encryption key formatted as 32-bit data from the encryption module into a plurality of units each with a wrapper providing information about the encryption message and a destination of the encryption message, wherein each unit is smaller than the maximum size, converts the encryption key 32-bit data of each unit into encryption key 16-bit data and corrects errors in the encryption key 16-bit data, relays the plurality of units to the at least one driver, removes the wrapper from each unit, and combines the plurality of units within the driver to form the encryption key formatted as 16-bit data.
