Improved certificateless sequential multi-signature scheme [PDF]

Tongxin xuebao, 2015
A sequential multi-signature enabled multiple users to jointly sign a document in order.Xu,et al proposed a provably-secure certificateless sequential multi-signature scheme with constant signature length and pairing computations.However,it was shown ...

Fair multi-party concurrent signature scheme [PDF]

Tongxin xuebao, 2014
Multi-party concurrent signatures were first proposed by Tonien et al at ISC2006,but Xie and Tan pointed Tonien et al's scheme doesn't satisfy fairness and they reconstructed multi-party concurrent signature schemes respectively.Through analysis,the ...

Efficient Multi-Signature Scheme Using Lattice

The Computer Journal, 2021
Abstract With the help of a multi-signature scheme, we can reduce the cost of storage and bandwidth in case of many signers signing the same message. Therefore, multi-signature schemes can be used in bitcoin to reduce the size of a blockchain. In this paper, we propose a lattice-based multi-signature scheme with the following highlighted

Digital multi-signature scheme based on bilinear pairing

网络与信息安全学报, 2016
Based on bilinear pairing and three complicated problems,a new digital multi-signature scheme was pro-posed.In the new scheme,the advantage of fast signature in broadcasting digital multi-signature was applied to se-quential digital multi-signature.By ...
