We present the first aggregate signature, the first multisignature, and the first verifiably encrypted signature provably secure without random oracles. Our constructions derive f...

Since the formalization of ring signature by Rivest, Shamir and Tauman in 2001, there are lots of variations appeared in the literature. Almost all of the variations rely on the ra...

We propose a secure threshold signature scheme without trusted dealer. Our construction is based on the recently proposed signature scheme of Waters in EUROCRYPT’05. The new thre...

Abstract. We show a new protocol for blind signatures in which security is preserved even under arbitrarily-many concurrent executions. The protocol can be based on standard crypto...

The ElGamal encryption scheme has been proposed several years ago and is one of the few probabilistic encryption schemes. However, its security has never been concretely proven bas...
