I wonder how quickly one could incinerate a memory card in the field with high success rate? Destroy the data and the passphrases don't help.
Smallish lithium battery has enough oomph to heat a NiCr filament (or charge an electrolyte capacitor to vaporize a thin filament) to detonate a pellet of lead azide or similiar. It will blow a hole in glass, or reliably destroy a flash chip, while being fairly safe when not held in hand (or embedded in a bulky enough case). This will produce a loud bang, obviously. Thermite is a good choice to turn your fileserver into lava, but that thing better be outside, or mounted in chamotte- or asbestos-lined metal closet. Will produce smoke, and take some time, too. If your keyring's been securely wiped, rubberhosing the passphrase out of you to unlock it will give the attacker very little. Assuming the device is powered on, and easily triggerable, that would be quickest. If you're just running a P2P which encrypts relay traffick, and a CFS hosting your warez and kiddie porn which needs interactive passphrase input to mount any forensics type people will only wind up with a glob of useless bits. Assuming the knuckle-draggers will know a CFS from a corrupted FS or a dead drive, that is. -- Eugen* Leitl <a href="http://leitl.org">leitl</a> ______________________________________________________________ ICBM: 48.07078, 11.61144 http://www.leitl.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE http://moleculardevices.org http://nanomachines.net [demime 1.01d removed an attachment of type application/pgp-signature]
