Cryptanalysis of and improvement on the Hwang-Chen multi-proxy multi-signature schemes
Hwang and Chen recently proposed new multi-proxy multi-signature schemes that allow a group of authorized proxy signers to sign messages on behalf of a group of original signers. ...

Time Capsule Signature: Efficient and Provably Secure Constructions
Time Capsule Signature, first formalized by Dodis and Yum in Financial Cryptography 2005, is a digital signature scheme which allows a signature to bear a (future) time t so that t...

A Secure Three-Move Blind Signature Scheme for Polynomially Many Signatures
Abstract. Known practical blind signature schemes whose security against adaptive and parallel attacks can be proven in the random oracle model either need five data exchanges bet...

Identity-based Threshold Signature Secure in the Standard Model
Recently, design of Identity-based (ID-based) threshold signature schemes which are efficient and provably secure in the standard model has drawn great concerns. In this paper, an...
