摘　　要：区块链技术为在分布式系统中建立安全、完整的数据传输提供了新思路,数字货币、金融、版权管理等领域已有借助区块链技术推动发展的趋势,但该技术在信息安全领域发展较为缓慢。基于部分组织管理敏感数据的不可篡改、私密化等要求,构建了基于私有链技术的信息安全防御系统框架模型,该模型分为应用层、共识层、网路层、数据层;系统设计的核心技术依托哈希函数的链式数据结构、Merkle树、P2P传输机制、ChainAchor身份认证框架以及MedRec访问控制框架。文中介绍了系统应用模式,包括存在证明、信息查询、信息追溯等。Blockchain technology provides new ideas for the establishment of secure and complete data transmission in distributed systems.The digital currency,finance,copyright management and other fields have already used blockchain technology to promote development trends,but the field of information security is relatively slow.Based on the requirements of some organizations to manage the tamper⁃proof and privacy of sensitive data,a framework model of information security defense system based on private chain technology is built,divided into application layer,consensus layer,network layer and data layer.The chain data structure of the hash function,Merkle tree,P2P transmission mechanism,ChainAchor identity authentication framework and MedRec access control framework;Finally,the system application mode is introduced.
