Re: [MirageOS-devel] BTrees, File System, Information Retrieval, and ORAM

The encryption layer is simply an application of the mirage-block-ccm library, which you can find here: https://github.com/sg2342/mirage-block-ccm

I have a forked version of the repository which is required for running my project.

Hi,

That looks great! Your slides mention block encryption but a (very) quick glance at the source code didn't seem to show an obvious place where this is done. Can you detail a bit more how the block encryption works or will work?

Thanks,

Thomas

Hi all,

I just wanted to let you know that I made the code for my Part II project publicly available at: https://github.com/ruhatch/mirage-oram

It is an implementation of the cryptographic primitive Path ORAM, satisfying Mirage's V1_LWT.BLOCK interface.

On top of BLOCK, I built an implementation of BTrees, which I then used for the inode index of a small File System. On top of that I built an indexing and search module that keeps an inverted index in the file system and does some simple phrase-query based search.

Currently this is all in one repo, but I plan to break it out into individual repos and push them to OPAM once I'm done with the project.

Feel free to take a look around and please let me know if you spot anything obviously wrong!

Kind regards,

Rupert
