AFAIK the PS3 doesn't have any controller security to speak of.
The security chip is required for ALL 360 controllers, wired and wireless. The Wireless also requires an additional encrypted wireless receiver/transmitter chip that they refused to license to anyone.
This is why the Team Xtender keyboard and mouse adapter requires you plug in a wired controller, it basically uses it for the security chip since Team Xtender couldn't get licensing to install the chip in their own product.
it's also why I had to use the guts of a 360 controller to do my Saturn adapter.
