一个前向安全的结构化多重签名方案

摘要

Based on the difficulty of computing discrete logarithm over finite field of large prime order, forward-secure technique is introduced into structured multisignature signature, then a new structured multisignature scheme with forward-secure is presented. It has not only characteristic of general structured multisignature, but characteristic of forward-secure .%　　基于有限域上计算离散对数的困难性，将前向安全的概念引入到结构化签名方案中，提出了一个新的具有前向安全性质的结构化签名方案。该方案同时具有一般结构化签名和前向安全签名的特点。
