A new type of proxy ring signature scheme with revocable anonymity and no info leaked

Abstract

In some real situations, we must apply proxy signature and ring signature both concurrently. In this paper, we present a new type of proxy ring signature scheme with revocable anonymity which allows the original signer to know exactly who the signer is and unlike other schemes, the original signer doesn't need to publish extra information except his original public key. It can play an important role in some real applications. © Springer-Verlag Berlin Heidelberg 2007.
