基于区块链的数据安全共享网络体系研究

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.

Block Chain Based Data Security Sharing Network Architecture Research

For the process of internal and external data sharing in energy Internet enterprises, there are centralized deployment, non-uniqueness identification, and theft or tampering to affect the efficiency of data asset sharing. Based on the character of decentralization, peer-to-peer and difficult-to-change, we 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, we 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 mechanism is described. Thirdly, we design the decentralized DNS (domain name sever) resolution module with ODIN. Then the part of system function is realized. And we analyze its performance.
