HARDWARE PROTECTION OF FILES IN AN INTEGRATED-CIRCUIT DEVICE

Abstract:

A method for the protection of files is performed on an integrated-circuit device that comprises a hardware memory protection module, which controls access to regions of the memory depending on region-specific settings. A new file is created in the memory by storing metadata and content data for the new file in a common memory region. An access condition is set for the common memory region in the configuration settings of the hardware memory protection module. A file is retrieved from the memory by searching the memory to identify a file meeting a search criterion. The searching involves comparing the metadata of files from the memory against the search criterion in order to identify a file from the memory that meets the search criterion.
