From: Alexander Klimov <[email protected]> Date: Mon, Feb 21, 2011 at 5:48 PM Subject: [cryptography] Reliably Erasing Data From Flash-Based Solid State Drives To: [email protected] <http://www.usenix.org/events/fast11/tech/full_papers/Wei.pdf>: We empirically evaluate the effectiveness of hard drive-oriented techniques and of the SSDs' built-in sanitization commands by extracting raw data from the SSD's flash chips after applying these techniques and commands. Our results lead to three conclusions: First, built-in commands are effective, but manufacturers sometimes implement them incorrectly. Second, overwriting the entire visible address space of an SSD twice is usually, but not always, sufficient to sanitize the drive. Third, none of the existing hard drive-oriented techniques for individual file sanitization are effective on SSDs. -- Regards, ASK _______________________________________________ cryptography mailing list [email protected] http://lists.randombit.net/mailman/listinfo/cryptography _______________________________________________ Freedombox-discuss mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/freedombox-discuss
