An identity (ID)-based signature scheme allows any pair of users to verify each other's signatures without exchanging public key certificates. With the advent of Bilinear maps...
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...

In 2003, Boneh, Gentry, Lynn and Shacham (BGLS) devised the first provably-secure aggregate signature scheme. Their scheme uses bilinear pairings and their security proof is in the...

Abstract. Known compact e-cash schemes are constructed from signature schemes with efficient protocols and verifiable random functions. In this paper, we introduce a different ap...
We introduce a new lattice-based cryptographic structure called a bonsai tree, and use it to resolve some important open problems in the area. Applications of bonsai trees include...
