Abstract:
A storage device includes encryption policies that may be applied to data stored thereon. Different encryption policies may be applied to different data on the storage device. Input/output (I/O) requests may identify the appropriate encryption policy to be applied using a data tag of the I/O request. The data tag may be applied by the file system when the I/O request is issued, or may be added by a filter driver before the I/O request is delivered to the storage device.
