Theory Question: Why isn't RSA a 0-knowledge Proof

[hallam at w3.org]

Zero knowledge means that the recipient obtains no information that they could 
not have obtained without knowing the secret information corresponding to the 
key. 

If I authenticate myself to you by giving a signature on a nonce you chose you 
have obtained information that you could not have obtained otherwise.


If it wasn't for the fact that it is IAP and you apear to be a grad student I 
might wonder about somone doing their course assignments via the net... :-)
