# Re: Random delay as a countermeasure to timing attacks

One possible hypothesis:
- the signal has a Gaussian distribution,
- the noise (the delay you add, plus any other random noise)
has a Gaussian distribution, and
- all of these contributions are independent.
Then it's easy to see that the S/N ratio goes up linearly
with the standard deviation of the noise, and goes down
proportional to the square root of the number of measurements,
