May I draw your attention to an old Gutmann paper that is still very much worth the read.http://www.cs.auckland.ac.nz/~pgut001/pubs/secure_del.htmlThere is another paper that is also worth the read but sadly I've lost the last reference to it I had.Deletion of data in RAM and even replacing it does not ensure that the old data is not recoverable.
Even the overwriting scheme proposed is not workable in practice, at least not for hard drives or compact flash media -- both of which silently remap sectors when "difficulties" are discovered, such that it is impossible to write to them again because they are invisible to the OS -- but they're visible to direct forensic examination. Only a CPA-IND encryption scheme in which keys are managed separately from the filesystem, and where a key-per-file scheme is in force, and where directories are similarly encrypted is there any degree of provable secure deletion. _______________________________________________ Full-Disclosure - We believe in it.
