| 摘 要： | 由于传统公钥基础设施(public key infrastructure,PKI)技术中心化的存储管理方式以及证书颁发、撤销不透明的特点存在着安全性问题,且多个CA机构之间互不可信,实现交叉认证具有一定难度,提出一种基于智能合约的去中心化身份管理及认证模型。通过基于区块链的智能合约实现用户多类型身份数据的发布、认证以及撤销,达到管理用户身份数据及在不同场景中根据不同的认证需求进行身份认证的目的。对模型的安全性进行了分析。

| Abstract: | The centralized storage management method and non-transparent nature of certificate issuance and revocation in the traditional PKI(public key infrastructure)technology result in security problems and mistrust exists among certificate authorities,hence it is difficult to achieve cross-certification.To resolve these problems,a decentralized identity management and authentication model based on smart contract was proposed.Through the blockchain-based smart contract,the user’s multi-type identity data were distributed,authenticated,and revoked,and the purposes of managing user identity data and identity authentication according to different authentication requirements in different scenarios were achieved.The security of the model was analyzed. |
