摘要

利用广义可验证秘密分享

提出了基于离散对数的公钥体制的密钥的分布式生成协议.该协议适用于任意的接入结构

具有需要各参与者保存的秘密信息的数据量小

能保证所生成的私钥的随机性和均匀分布性等特点.因而与通常的基于门限接入结构的分布式密钥生成协议相比能够更广泛的应用于群体密码学中的各种场合.

Abstract

A distributed key generation protocol for public key cryptosystem based on discrete-log is proposed using generalized verifiable secret sharing.The protocol is applicable to arbitrary access structures

and has the following properties:the amount of secret information needed to be stored by each participant is small

and it can guarantee the randomness and uniformity of the distribution of the generated secret key.Hence it can be more widely used in group oriented cryptosystems than those protocols based on threshold access structures.
