If they dumped them the market would crash. An increase of available bitcoins for sale of 13% would cause a massive crash.
Sure. Just set the value of all bitcoins to 0. Just imagine the fun that would be.
"Sorry but a lot of us decided to take your money away from you because we do not like you."
I did read the entire paper. Using the methods they used it does not seem to be a practical attack vector at all. In fact I would say that you would have to have detailed specific information of the computer being exploited. Not even just the model but the actual computer since things like the age of the caps will make a difference.
On a danger scale of 1 to 100 this is about a 1. I should have made it more clear that I was more suggesting that this is wildly impractical verses theoretically impossible. Frankly it might even work one week and not the next.
I get that and the length of time to extract the data all would seem to make this a very improbable method for a practical exploit.
I did and it just doesn't make any sense.
Where does the sound come from? Their answer is this.
"The acoustic signal of interest is generated by vibration of electronic components (capacitors and coils) in the voltage regulation circuit, as it struggles to maintain a constant voltage to the CPU despite the large fluctuations in power consumption caused by different patterns of CPU operations. "
The variable power load would very based on the instructions but we are not really interested in the instructions we are interested in the data. Doing an instruction on any data should cause the same power draw so how do they extract the data?
Then you have answer 8
"Individual CPU operations are too fast for a microphone to pick up, but long operations (e.g., modular exponentiation in RSA) can create a characteristic acoustic spectral signature over many milliseconds, and these can be detected. In the chosen-ciphertext key extraction attack, we carefully craft the inputs to RSA decryption in order to maximize the dependence of the spectral signature on the secret key bits."
So it can only work with some keys?
For the multi core issue CPUs have a single VCC so you have no idea what core is doing want if it is even possible to extract the pattern since the claim it is the power draw on the voltage regulators that cause the sound.
The summary really does not answer the questions. The idea that the sound can extract the data violates the Nyquist–Shannon sampling theorem. There should be no way a multi khz audio signal can carry the data of the exection of data at over 1 Ghz. Even the statement that they extract the key over half an hour is just illogical. How much data can a modern PC encrypt with half an hour execution time?
What sounds does a cpu make? Or better yet how does a CPU make sound? The clock speeds are in the GHZ range so it is so far outside of the sound range of any microphone it just is not funny.Throw in that all cpus today have more than one core you will have a more than one code stream executing at one time. Throw in the sound of the fans running to make picking up the sound just seem very unlikely. Until it is duplicated I would really doubt it.
"His mistake was admitting it."
And this is what is wrong with the world. His mistake was calling in a bomb threat to get out of taking an exam.
I have a different take. I do live in Florida so heat is bad. The thing is that I can not find really bright LEDs? I want a bulb that is at least as bright as a 100 watt bulb.
More likely they just got lucky.
You would be more of a two minute clock. 1000 Rems is around what it takes to kill you dead. Mounting it in the front of a cars bumper with shielding behind it might work or even pointing out the side of a car. Drive around NYC in traffic and get pedestrians as you go.
Are the poles on public ride of way. If so then to bad for AT&T.
"Besides, without an atmosphere, who'll care?" Just one of the many much bigger problem that I was talking about. That and earth exploding and the sun going out.
Some lumps of moderator at the bottom of the tank will not really be an issue. Of course a massive family of tornados could hit a wind farm and the blades could take out every elementary school of a city and kill of the children.
AKA your fears are will in the super freakish events area that are in the same range of probability of a meteor strike.
Yes but the molten salt and the storage container will act as heat sinks. The fuel is in the mass of the salt and not contained in the fuel rods. Not to mention that the fuel is already melted so no worry about a meltdown damaging the fuel rods. No water to boil, the fuel is in the coolant, and no possible steam explosion and it all works at one atmosphere.
The design uses a "salt" plug that is cooled. Cooling shuts off the plug melts and the fuel drains into a tank that lacks a moderator so the reaction stops. There is no water to boil and fuel is already melted. It will then cool and solidifies.
As long as you have gravity then you are good. Now if all of a sudden gravity stops working then we have much bigger problems.
