Port aircrack-ng to Cell Broadband Engine

[mb]

Hi,

Here's an early and incomplete patch to port aircrack-ng to the Cell Broadband Engine (Playstation 3).

It currently only supports WPA cracking. (However, I'm not even sure if it's worth to implement WEP cracking, as PTW is so fast anyway).

So, well. The code still has serious speed issues, but it basically works. On the playstation we get a speedup of about 2.3, compared to running an unpatched aircrack-ng on the PS3. So it's not _that_ bad.

However, I only get half the speed on the (patched) PS3, compared to a Quad Power-Mac with 2.5GHz. I think this can be improved. I'm working on it...

Don't commit this. I will commit this when it's done. This ticket is just for comments.

I added an optimized patch, which goes up to a speed of 340keys/s. Which is 3.5 times the speed compared to running aircrack-ng without the patch on the cell. Still some changes needed to the code... I will remove the existing WEP stubs and calc WEP on the PPEs only. I think it's not worth it.

I created a branch for it but I didn't committed the patch (it's a WiP): branch/aircrack-ng-cell

Do not hesitate to commit there if you want.

Hi there!

I wanted to work in a version of the PTW attack for the Cell/BE but first I wanted to know if this already exists. I've been surfing the web and all I found is this comments and the unchanged branch you talk about.

Do you have any idea if there's anything done on attaking WEP with Cells ported to aircrack?

Thank you!

Check out branch/aircrack-ng-cell in our subversion.

Isn't it the same than the trunk?

I can't find any significant difference... Maybe I am doing something wrong or looking at the wrong svn... is it in 'trac.aircrack-ng.org/svn/branch/aircrack-ng-cell' ??
