Scheme for Assured Protection and 1-sec Deletion of Large Volumes


ABOUT THIS PAPER PUBLICATION

Overwriting a disk is totally unnecessary. A long time ago I had to worry about forensics and independently developed an idea that existed in academic literature: loosing encryption key = loosing all the data. So long as disk encryption is done right, one destroys 256-1024bits (key+administrative stuff) instead of, say, a thousand billion bits. The time taken was reduced from nearly a day to seconds. The scheme combined free/cheap disk encryption and software that generated master key from a password and a long random string, stored in a coprocessor's memory, a usb key or on rice paper.
