You can get special paints formulated specifically for concrete flooring; they are very hard wearing and grip the surface well. Ask in DIY shop for the right product, and follow instructions on the tin. There is a sort of concrete primer paint, too.
The other usual things apply when painting the floor, try to make sure the surface is as clean as possible, and smooth -- it might even be worth sanding it down.
The paint will wear off over time, though; it's inevitable if the floor receives daily use. So you're looking at scrubbing and sanding and re-painting it again, every few years.
Speaking from experience, though, I would be inclined to mix dye in with the concrete before it were laid, instead. And then paint on top of that in a similar colour. You'll get the smoother texture of a paint floor, but it won't look as bad in between re coats because the concrete underneath will be close to the same colour.
