摘要

基于离散对数计算和大整数分解的困难性

利用RSA加密体制提出了一个新的门限多秘密分享方案.该方案通过零知识证明等协议来防止秘密分发者和秘密分享者的欺诈行为

因而是一个可验证的门限多秘密分享方案.该方案还具有:秘密影子可重复使用;子秘密影子可离线验证;供分享的秘密不须事先作预计算等特点.该方案可用于会议密钥(秘密)分配、安全多方计算、门限数字签名等应用领域.

Abstract

A new multiple secrets sharing scheme

based on the intractability of the discrete logarithm (DL) and the RSA encryption algorithm is presented

in which the participants' shadows remain secret and can be reused

even if all subshadows are made public.Meanwhile

by using a zero-knowledge proof protocol

the validity verification of shadow and subshadow is also provided to prevent both dealer cheating and other participant cheating

and any freely given secrets without pre-computation by dealer can be reconstructed.The scheme can be applied to many areas such as conference key distribution

secure multi-part-computation

threshold signature etc.
