Abstract
An electronic signature is generated in a predetermined manner and attached to a transferable unit of write data, to facilitate authenticating the write data before allowing the write data to be written into a protected non-volatile storage. The write data is authenticated using a collection of secured authentication functions. Additionally, the actual writing of the authenticated write data into the protected non-volatile storage is performed by a secured copy utility.
