基于区块链的数据安全共享网络体系研究

Block Chain Based Data Security Sharing Network Architecture Research

针对能源互联网企业内部与外间的数据共享过程中,存在集中部署访问受限、标识不唯一、易被窃取或篡改隐患等问题,影响到数据作为资产进行统一安全共享的效率.为此,结合区块链的去中心化、自主对等、难以更改的技术特征,构建基于区块链的数据安全共享网络体系,主要包括去集中化数据统一命名技术及服务、授权数据分布式高效存储和支持自主对等的数据高效分发协议.其次,设计了开放式数据索引命名结构,含一级基础ODIN和多级扩展ODIN,且阐述了开放数据索引命名运行机制.再次,基于ODIN技术,设计了基于ODIN的去中心化DNS的域名协议模块,为数据间P2P安全可信共享奠定基础.最后,针对基于ODIN的去中心DNS的功能进行验证,为实现企业内部及企业间的数据安全共享构建了一种可信网络环境.

For the process of internal and external data sharing in energy Internet enterprises,there are centralized d e p l o y m e n t,non-uniqueness identification,and the tt or tampering to affect theefficiency of data asset sharing.Based on the character of decentralization,peer-to-peer and difficult to change,w e construct data security sharing network architecture base on block chain to support exchange information for internal and inter-enterprise.It is to achieve a trusted network environment with the distributed storage.Firstly,w e propose a block chain based data security sharing network architecture,including decentralized data unified naming technology,authorized data distributed storage and data distribution protocol.Secondly,an open data index naming structure(ODIN)is designed,including single-level basic ODIN and multi-level extended ODIN.And then ODIN operation mecha is m is described.Thirdly,w e design the decentralized DNS(domain name sever)resolution module with ODIN.Then the part of system function is realized.And w e analyze its performance.
