摘　　要：文章针对区块链技术在数字图书馆信息安全应用中出现新特点和技术优势,探讨了数字图书馆无中心网络信任安全问题,采用区块链共识算法设计一种网络传输信息安全和区块链结构的数据安全传输模式。针对传统公钥CA认证中心操作记录难公开、不透明等问题,文章结合区块链技术分布式存储、数据加密技术及云数据多租户特征,提出图书馆数字证书管理过程可审计且扩展的高可信度用户认证机制和个人数据保护模型,从而构建可信区块链的数字资源存储与共享安全架构,并从安全认证、可扩展的安全多方计算、完整性保护等方面,给出区块链下图书馆数字资源安全防护保障策略。Based on the new features and technical advantages of blockchain technology in the application of digital library information security,this paper discusses the problem of digital library network trust without center,and uses blockchain consensus algorithm to design a network data security transmission mode with network transmission information security and block chain structure security.In view of the problems of the traditional public key CA authentication center,such as the difficulty to open and opaque operation records,the blockchain technology combines the distributed storage,data encryption technology and the multi tenant characteristics of cloud data.This paper puts forward the high reliability user authentication mechanism and the personal data information protection model which can be audited and expanded in the digital certificate management process of the library.This paper constructs the security architecture of digital resource storage and sharing based on trust blockchain,and gives the protection strategy of library digital resource security system based on blockchain from the aspects of security authentication,scalable security multiparty computing,integrity protection,etc.
