摘要(Abstract):
数据作为一种重要的生产资料已经成为产业发展的重要驱动力.为了挖掘各行各业产生的海量数据的潜在价值,多方数据共享成为许多行业的迫切需求.但是传统的多方数据共享方案大部分基于第三方云存储服务,这些方案的数据存储和传输媒介存在数据过于集中的缺点,容易出现单点故障问题和数据安全问题,并且存储和下载需要支付高昂的费用;并且,传统的中心化数据共享方案在多方数据共享时,难以在保证数据安全性的同时提供高效的数据加密.为解决以上问题,本文提出了一种基于门限代理重加密和星际文件系统(IPFS)的数据去中心化安全共享的方案,实现了在存储层和加密层的去中心化,解决了单点故障问题;并且在多方数据共享的情景下提高了数据传输性能和数据加密性能.实验结果表明了该方案的可行性、高效性和安全性.
