Oblivious Filesystem

[ghackebeil]

This would be an interesting project. That is, take the block storage interface in PyORAM and create a wrapper class that provides a filesystem interface (perhaps a backend for PyFilesystem). One would need to:

• implement reasonable caching strategies for frequently used blocks
• keep track of unused blocks
• efficient mapping of file objects to blocks (perhaps with block sub-allocation strategies)
• etc.

This is somewhat duplicating work that would be handled automatically if we were implementing a kernel driver, but the point of this project is to avoid development in C.
