Meaningless Weakness Found …
Posted in security on March 7th, 2010 by irv – Be the first to commentIt seems that everywhere I look lately there’s news about a new “weakness” found in the RSA algorithm. This has been reported with headlines screaming about the “severe” weakness and how everything in the universe that is encrypted depends on RSA. For examples of those rather overheated stories look here and here.
Let’s have a moment of sanity please. The sky is not falling. The attack described depends on manipulating the power supply of the targeted system, making tiny changes in the voltage to generate bad output from the algorithm. It’s a very interesting attack technique but the actual risk of it happening in the real world is incredibly low. Anyone who can get close enough to manipulate the power to a unit can do lots of other much more interesting things to it.
In general, no one can get close enough to perform this kind of attack. Locking the doors on the server rooms is a standard IT practice. You see, most criminals who get close enough to attach the equipment needed to play games with the power supply are much more likely to simply unplug it and steal the computer. We guard against that sort of thing and, incidentally, against creative attacks on the power as well.
This is just one more example (in a nearly infinite list) of why the news should never be taken at face value. Read carefully. THINK. Apply salt liberally and move on to something less ridiculous.
