comment Authentication mechanism for low memory, low computing power device
If you can't even do AES at all, I'm not sure how you think you're going to implement any kind of zero-knowledge proof. There's very little practical crypto you can do with devices that limited. (Then again, it's also possible that you're just underestimating the performance of your processors; even many smart cards can do AES nowadays.)

comment Authentication mechanism for low memory, low computing power device
You might want to add some more details to your question. For instance, who/what do you want to authenticate to whom, what kind of keys/passwords/tokens do they share, what kind of processor are you talking about ("low" can be relative), and what kind of attack scenarios are you expecting?

@Layla: I just tried to do that myself, but feel free to change anything you want (especially if you feel I introduced any inaccuracies). It's your question, after all.
