Asymmetric Concurrent Signatures
The concept of concurrent signatures allows two entities to produce two signatures in such a way that, the signer of each signature is ambiguous from a third party’s point of vie...

Compact E-Cash from Bounded Accumulator
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...

Ring Signatures of Sub-linear Size Without Random Oracles
Ring signatures, introduced by Rivest, Shamir and Tauman, enable a user to sign a message anonymously on behalf of a “ring”. A ring is a group of users, which includes the sign...

A Provably Secure Proxy Signature Scheme in Certificateless Cryptography
A proxy signature scheme enables an original signer to delegate its signing capability to a proxy signer and then the proxy signer can sign a message on behalf of the original sign...

Signature Schemes and Anonymous Credentials from Bilinear Maps
Abstract. We propose a new and efficient signature scheme that is provably secure in the plain model. The security of our scheme is based on a discrete-logarithm-based assumption p...
