    Hi all,

    I am developing a secure encrypted filesystem on a usb pendrive. It
    would encrypt and then store data in pendrive. Access to this
    filesystem needs to be password protected.

    I am working on mandrake 10.1 with kernel 2.6.9 series.

    Can anyone tell me what approach should i follow here? Is modifying the
    original pendrive's driver so that every read and write operation will
    do decryption and encrytion respectively and user level access controls
    to be done via IOCTL calls, a good approach?

    OR do I have to write a new virtual device driver to be running on top
    of the pen drive's driver for realizing this file system. Is there a
    base driver present in Linux source that i could use to build this
    secure file system?

    I would be thankful for any help/pointers

    bye,

    shiva
