Hi,

currently I m trying to follow the Wiki tutorial about breaking RSA
https://wiki.newae.com/Tutorial_B11_Bre ... the_Attack

Now here's my Problem:

My power trace looks like this:

But it should look something like this:
Image

I am pretty sure that I followed the whole tutorial and configured everything right. Could you give me some suggestions and help, please?

btw. the automated attack script from the Wiki works just fine for me if I use the provided example traces from https://github.com/newaetech/chipwhisperer-examples but if I try to attack my captured traces it fails.

This is what my saved settings look like:
