基于配对函数的顺序相关多重数字签名

Dependent Sequential Multiple Signatures Based on Pairing Function

基于配对函数和陷门同态置换的签名聚合方法提出了安全的顺序相关的多重数字签名方案,具有以下特点:利用配对函数来记录签名顺序,使得签名可依序进行;签名人数不受限制;签名较短、签名和验证过程简单;无须第三方为每次签名生成密钥以及签名者的编号等。该方案可用于电子商务、电子政务中。

Based on the pairing function and trapdoor homomorphic permutations method to aggregate the signatures,a dependent sequential multisignature scheme is presented.This Scheme possess of the following properties:the multiple signatures is ordered by using the pairing function;no limitation to the number of signers;the final signature is relatively short;the process for signature and verification is simple;and it is not necessary for a third party to generate the key and decide the order of signers.It can be applied to the E-commerce and E-government.
