Some Thoughts on Strong Unforgeability in Ring Signature Schemes

摘要：

A signature scheme is strongly unforgeable if the adversary cannot produce a new signature even on a queried message. Some methods have been proposed to enhance some regular signatures. However, if applied to ring signatures, such methods will break the anonymity, which is the soul of ring signatures. We introduce a modified method which can achieve both strong unforgeability and anonymity in the standard model. Applying this method to Shacham-Waters scheme, we get the first ring signature with strong unforgeability in the stand model.
