Original Abstract Submitted
Techniques are disclosed relating to securely storing file system metadata in a computing device. In one embodiment, a computing device includes a processor, memory, and a secure circuit. The memory has a file system stored therein that includes metadata for accessing a plurality of files in the memory. The metadata is encrypted with a metadata encryption key that is stored in an encrypted form. The secure circuit is configured to receive a request from the processor to access the file system. In response to the request, the secure circuit is configured to decrypt the encrypted form of the metadata encryption key. In some embodiments, the computing device includes a memory controller configured to receive the metadata encryption key from the secure circuit, retrieve the encrypted metadata from the memory, and decrypt the encrypted metadata prior to providing the metadata to the processor.
