comment Non-interactive Zero-knowledge proof signature validation without public key
thanks for the answer. to clarify my scenario. it's about an e-coin system like bitcoin. i used the signing as a synonym here, not the actual signing that we know. what i want to achieve is, that A sends coins to B. but i have to make sure that only B can spend the coins. The message from A could be encrypted with Bpub, but B would have to release his pub key and sign the message to proof that only he can decrypt the message from A. But i want to keep it anonymous, that B doesn't have to show his identity when sending coins like in ZeroCoin
