摘要:

数据共享与数据分发是社会发展的必然趋势,与此同时,由数据共享引发的安全问题同样需要关注。区块链具有可溯源、不可篡改的特性,可以有效解决传统数据共享与分发方案带来的单点故障问题,同时保护数据安全。文章提出一种基于区块链和密码学的数据安全共享与受控分发模型,模型包括数据上传算法、数据共享算法和数据分发算法,采用IPFS存储数据,利用区块链记录数据从上传到共享与分发的整个过程,具有良好的可追溯性,可充分保障数据的安全。

关键词: 区块链, 数据共享, 数据分发, IPFS

Abstract:

Data sharing and data distribution is the inevitable trend of social development. Meanwhile the security issues caused by data sharing also need to be concerned. Blockchain has the characteristics of traceability and non-tampering, which can effectively solve the single point of failure problem caused by the traditional data sharing and distribution scheme, and protect the data security at the same time. This paper proposed a data security sharing and controlled distribution model based on blockchain and cryptography, including data upload algorithm, data sharing algorithm and data distribution algorithm. IPFS is used to store data, and blockchain is used to record the whole process of data from upload to sharing and distribution, which traceable and fully ensures the security of data.

Key words: blockchain, data sharing, data distribution, IPFS
