摘　　要：由于传统认证系统中心化的结构存在安全问题,作者提出了一种在去中心化的以太坊平台上设计身份认证系统模型的思路。根据区块链技术特点和以太坊的技术架构,结合身份认证系统的主要功能,设计了基于以太坊平台架构的身份认证系统模型,通过任务集合和关系向量对身份认证模型进行描述。编制可以操作区块链账本的智能合约,开发能调用智能合约的本地程序,在Bossa引擎中注册认证模型,完成以太坊网络环境的搭建和认证模型的部署,实现了基于以太坊智能合约的身份认证模型的应用。设计和实现去中心化身份认证模型,能够彻底解决中心化认证系统的安全隐患。To solve he security problems of traditional authentication system due to its centralized structure,an idea of designing identity authentication system model on decentralized Ethereum platform was proposed. According to the characteristics of block chain technology and the technical architecture of Ethereum,combined with the main functions of identity authentication system,an identity authentication system model based on Ethereum platform architecture was designed and described by task set and relationship vector. In the process,a smart contract that could operate the block chain ledger was written and a local program that could call the smart contract was developed. The authentication model was finally registered in the Bossa engine. The design and implementation of the de-centralized identity authentication model can completely solve the potential safety hazard of the centralized authentication system.
