Research on Information Management Framework of Big Data Based on Security Cloud

近年来,随着信息技术的不断发展,对海量数据的高效率处理与分配成为研究热点,由此引申出的基于云计算的大数据存储链条安全机制问题更为凸显。本文提出了一种基于松耦合下的细粒度访问控制架构模型,从云计算环境下大数据组件访问依赖集合、基于同态加密机制的安全云计算、基于实时动态群签名的大数据共享方案等角度研究了基于安全云计算的大数据信息管理框架。仿真验证表明,本文所提基于安全云计算的大数据信息管理框架在大数据存储安全性、加密处理速度、数据存储空间等方面具有较为明显的优势。

In recent years,with the continuous development of information technology,efficient processing and allocation of massive data has become a research hotspot.The security mechanism of large data storage chain based on cloud computing is more prominent.This paper presents a fine-grained access control architecture model based on loosely coupled.The large data information management frame based on secure cloud computing is studied from the following aspects:large data component access dependency set in cloud computing environment,secure cloud computing based on homomorphic encryption mechanism,and large data sharing scheme based on real-time dynamic group signature.Simulation results show that the proposed large data information management framework based on secure cloud computing has obvious advantages in large data storage security,encryption processing speed,data storage space and so on.
