Out Of The Stone Age

XSFS: The Extensible Steganographic Filesystem is a term paper I wrote in the first semester of my Masters program in CS at USC. I wrote it for CS555: Advanced Operating Systems in Fall 2004. The ideas in XSFS are especially useful when needing to hide large amounts of data on untrusted storage.

It would make an interesting project to clean up the ideas a bit and modernize it for untrusted storage such as Amazon S3.  It would also be a really excellent project to implement in Erlang.

Oh, and sorry for the picture. It was originally done in MS Word on the school computers for some unknown reason, and has been shuffled through various versions of OpenOffice for some time. I’m sure I have the original on CD somewhere, but for now you’ll have to take this slightly edited version.

I’ve been using OpenBSD since the 4.3 release and am starting to track -current. I’ve also been heavily coding in Erlang lately. CVSsup seems like it might be able to receive a performance boost from the lightweight process model of Erlang.  I haven’t looked too closely at the protocol yet, but this seems like it might be an interesting and useful thing to try.
