Well, this is huge, so I'd like to draw your attention to what's happening right now. This is a very alarming case, and it concerns every ad blocker user.
A core, not side, effect of technology is its ability to magnify power and multiply force — for both attackers and defenders. One side creates ceramic handguns, laser-guided missiles, and new-identity theft techniques, while the other side creates anti-missile defense systems, fingerprint databases, and automatic facial recognition systems.

If security won’t work in the end, what is the solution?
Resilience — building systems able to survive unexpected and devastating attacks — is the best answer we have right now. We need to recognize that large-scale attacks will happen, that society can survive more than we give it credit for, and that we can design systems to survive these sorts of attacks.
Je résume donc mon opinion « un réseau pair-à-pair sans composant central (ou hiérarchique) ne peut PAS être sécurisé contre les attaques Sybil ».
A lot of press has been released this week surrounding the cracking of MS-CHAPv2 authentication protocol at Defcon. For example, see these articles from Ars Technica and CloudCracker. All of these articles contain ambiguous and vague references to this hack affecting Wi-Fi networks running WPA2 security. Some articles even call for an end to the use of WPA2 authentication protocols such as PEAP that leverage MS-CHAPv2.
But they fail to paint a true and accurate picture of the situation and the impact to Wi-Fi networks. I think this is misleading, and that any recommendations to stop using PEAP are flat-out wrong!
So let's clarify things.
