        Introduced in the `NetBSD -current' source code tree and part of
        the upcoming 2.0 release, the CryptoGraphic Disk Device (CGD)
        provides cryptographic security for data stored on hard drives.
        The presentation will cover the following:

                1.  the high level design of CGD,
                2.  threat models,
                3.  comparison with both other cryptographic disk
                    drivers and file systems, and
                4.  how to use CGD, and make sure that you are
                    using it securely.

        For background information on CGD please refer to

    For those interested in trying this in OpenBSD or perhaps helping to improve the port to OpenBSD... I found this so far.

    I for one would love to see this native in OpenBSD as well - aside from vnd of course. ;-)

    Regards.

      Thanks for the link, I'll bring it to the attention of Roland, just in case he's unaware of it.

        Do you know if there'll be any slide shows available online afterwards, of this presentation?

        I would love to go but I think it's about an 8 hour drive from Montreal... :-(

          8) Better than that, we are going to videotape it, and make it available off the Web. Check the site (http://www.nycBUG.org/) after the meeting, give it a day or two, in case.

          And, Man, about slides, all you to have do is ask, especially since you are such a trooper! 8) If we have slides I'll make sure you get a copy, or you can get them off the site.

            The NetBSD cgd meeting went very well.

            You can get the link to Roland's paper, some pictures of the meeting, and in the near future, a video of the meeting and slides.

      I noticed the port a while ago. I am actually quite surprised that it has not been brought into the main OpenBSD tree as they honestly have nothing that offers similar functionality.

      vnd+crypto is trivially vulnerable to offline dictionary attacks and hence should not be considered even marginally secure unless you are taking great care with your passwords. In fact, OpenBSD's vnd+crypto is easier to crack than /etc/master.passwd which is the reverse of what you would expect...
