please help me find a CPA (Correlation Power Analysis) attack against the montgomery scalar multiplication algorithm, either in VHDL or Matlab

Sigh. It's sad to see this once wonderful forum being reduced to this--a forum for students to request for help in all of the wrong places.

• Did you check any of the cores on OpenCores for what you needed?
• Are you intending to contribute to OpenCores with a core of your own?
• Are you attempting to use someone else's core posted here, and struggling?

This appears to be one of a large nummber of forum posts that are just so completely off topic that it's sad to watch them go unanswered--as this one probably will be.

The three topics above are probably more appropriate requests of this forum, although I've only seen mixed results from the third type of query--not all of the contributors to OpenCores are still around. In other words, this forum is not a library. If you need library materials, and it sounds like you might, please inquire of your local librarian.

If you wish to hire an expert, you might even be able to find one here.

As to the request of the original poster, you can try Google. A quick search turned up several articles.

As to your urgency, I know of another student who needed help too:

I need a codes for a fluxes capacitor. Specs: It must be able send a message 8.64e+10 uS into the past. I like Verilog it has been goods to me.

The fluxes capacitor must be implemented in a state machine because that's what my thesis'is director advised. I must have this by 2 weeks to get my degree.

With this code I will be able to tell myself if I passed or not.

Thanks.

I was actually wondering today if he ever got his degree ...
