Hello,
After many spectra attacks, I think it's time I told you about my latest th oughts or even invention.
The formula:
Information = Time * States
Could also be thought of as :
Information = Time * Delta States
I am starting to believe there is a relation ship/link between information and time.
And since computers are basically states transition machines which work wit h operations to changes these states. The information that is produced over a time period happens by state changes, hence delta S.
I am not a math guy maybe there is a better way to formulate this formula.
This formula does make it obvious then when reducing delta S to it's minimu m for example 1 state change, the time for this operation becomes observabl e, since each operation may require different time, information is leaked ( the time can identify the operation, maybe even the data).
This also predicts that there is another implicit attack vector (after all these spectre attacks which so far have used timing attacks to acquire info rmation).
Since computers use energy to transform states and do operations each opera tion/state change could use up a certain ammount of energy.
Thus the ammount of energy used could also leak information about the opera tion/state inside the machine.
Computers/Machines currently use voltage/watts and that kind of thing, whic h can be seen for example by hardware monitor tool.
Thus I have begone to wonder if the frequency at which this data can be rea d is high enough to start profiling "operations of the cpu/machine" based o n energy usage or in this case on "voltage fluctuations".
The voltage fluctuations may be another way to "transmit" data from the cpu /process to another process. It could be the next line of "spectre attacks" .
If the given formula above is correct then I can basically come to the conc lusion that computers are basically inherently "leaky" ("flawed" for storin g information securely).
There never was a thorough examination of the security of "turing machines" , Alan Turing died before he could work on this examination.
We may now have entered a society/world were all our information store on c omputers is inherently leaky.
Bye, Skybuck.
