Abstract
A technique for securing a flash memory block in a secure device system involves cryptographic techniques including the generation of a Message Authentication Code (MAC). The MAC may be generated each time a file is saved to one or more data blocks of a flash memory device and stored with the file's metadata and to each of the data blocks. A technique for reading and storing versioned files may be employed when applications utilize versioning.
