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.
