I was at the conference where they presented this. I'm actually in charge of the conference website (Wolfgang Richter, http://sigops.org/sosp/sosp13/cfp.html#pc http://sigops.org/sosp/sosp13/cfp.html#pc). At the conference, and in the paper title/abstract, it did not seem that _security_ was a focal point, or even a point, of their design. I understand already that they protect the _integrity_ of data---but I feel like that should be a given for any modern file system anyways. I am more specifically interested about the security of the file system in general. How does it secure data in a distributed setting? Is there anything new and cool there?
