Title: Does Bitcoin Encryption Need to be Updated?
Post by: BADecker on December 25, 2013, 04:52:25 PM
Seems someone has found a method to break the toughest encryption around by listening to the sounds the harddrive makes while decrypting.

We've already seen this on this forum. If you notice, the attack mentioned doesn't even affect the algos bitcoin uses (SHA and ECDSA). Why replace your Toyota if suddenly Fords were catching fire?

Even if this method was applicable to the algorithms used by bitcoin it is a much less significant threat then what we already know exists out there.  For instance the back doors available to NSA employees built into the Mac and Windows operating systems.  Couple that with the fact that it has been revealed that NSA employees, even those without security clearance, have had free reign to use communication spytools for personal use, spying on the spouse suspected of cheating, stalking the love interest etc...  Take that knowledge and look at the Mac/Windows downloads vs the linux downloads for bitcoin-qt: http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.8.6/

Bitcoin does not use encryption.

Bitcoin does not use encryption.

... except for the (optional) Bitcoin-QT wallet encryption. Nevertheless, this attack doesn't seem to be a thereat to Bitcoin.
