Good day to everyone.
I am trying to implement an e voting system (just for reference -it is not important though-it is described at the Internet Voting Protocol Based on Improved Implicit Security by Abhishek Parakh & Subhash Kak Version of record first published: 29 Jun 2010. ).
The protocol I am trying to implement mentions that "The Polling Station verifies the validity of Voter-id by conducting a zero-knowledge challenge-response protocol with the Registry Authority to validate the signature of voter-id."
I have searched at Google, and at Wikipedia about this protocol, but I didn't get much information. It is very important for me, to learn about what is this protocol, and what Polling station has to sent to Registry Authority, and what Registry Authority has to send back. Basically, I need to know how I can achieve to validate the voter-id.
Thank you very much for your time.
