摘要:

为了有效解决传统PKI体系中存在的CA交叉认证及单点故障等问题,提出了一种新的身份认证机制。首先,基于区块链技术构建基本架构,通过动态生成可信节点来构建可信联盟;其次,提出全网统一的唯一身份标识ID并采用SRT数据结构存储;最后,通过双层共识机制全网节点皆能进行统一身份标识认证。实验表明,本机制能够满足海量用户身份信息的查询和管理,并且能够保证身份认证过程中的高效与安全。

Abstract:

In order to effectively solve the problems of CA's cross certification and single point of failure in traditional PKI system,a new identity authentication mechanism was proposed.Firstly,this mechanism built the basic architecture based on blockchain,and built the trusted alliance by dynamically generating trusted nodes.Secondly,the whole network unified unique identity was proposed and used a new data structure,named SRT,to store.Finally,all nodes in the network could mutual authentication through the double layer consensus mechanism.Experiments show that this mechanism can meet the query and management of massive user identity information,and ensure the efficiency and security in the identity authentication process.

Key words: blockchain, trusted alliance, identity authentication
