Re: perfect zero-knowledge

Hi again,



I read in some older postings, that the zk-proof (equality of two 


discrete logarithms) of chaum and pedersen in "Wallet Databases without 


observers" is only statistical zero-knowledge. In the paper of Chaum & 


Pedersen, they mention that no information is gained by running the 


protocol, so it should be perfect zero-knowledge. What is the right? And 


why?



Thanks for your help!
