We construct new multi-signature schemes that provide new functionality. Our schemes are
designed to reduce the size of the Bitcoin blockchain, but are useful in many other settings …

We construct new multiparty signature schemes that allow multiple signers to sequentially
produce a compact, fixed-length signature simultaneously attesting to the message (s) they …

The focus of this work are multi-signatures schemes in the synchronized setting. A multi-
signature scheme allows multiple signatures for the same message but from independent …

Acting as an important part of Internet of Things (IoTs), vehicular ad-hoc network (VANET)
has attracted considerable attention in recent years, where the emergency reporting system …

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 …

Multisignatures enable multiple users to sign a message in an interactive manner. Many
instantiations are proposed for multisignatures, however, most of them are quantum …

We introduce compact certificate schemes, which allow any party to take a large number of
signatures on a message M, by many signers of different weights, and compress them to a …

The issue of automation of information technology support for distance learning is the
subject of many studies and heated discussions among scientific and pedagogical workers …

The notion of concurrent signatures was recently introduced by Chen, Kudla and Paterson.
In concurrent signature schemes, two entities can produce two signatures that are not …

摘要基于因数分解和二次剩余困难性假设, 构造了一个新的按序多重数字签名方案和广播多重
数字签名方案. 新方案的特点是: 多重签名不是由签名成员所生成的多个单签名的累加 …
