基于云计算的大数据安全保护技术研究

Research on Big Data Security Protection Technology Based on Cloud Computing

互联网技术的快速发展为人们的生活带来了巨大的便利,云计算技术和大数据技术的发展使得数据管理与分析方法得到了很大提高,为信息数据时代的发展提供了巨大的技术支持,但是数据传输与储存的安全问题限制着云计算和大数据的技术发展。研究现在通用的加密技术,探讨由对称加密和非对称加密技术结合的混合加密技术,分析其加密、解密机制及通信模型,发挥二者的优点,使得在数据传输与储存时既能达到较高的加解密效率,又能保证数据安全。

The rapid development of Internet technology has brought great convenience to people’s life.And the development of cloud computing technology and big data technology makes data management and analysis methods have been greatly improved,which provides great technical support for the development of information data era.However,the security problems of data transmission and storage limit the technological development of cloud computing and big data.This paper studies the current common encryption technology,discusses the hybrid encryption technology combining symmetric encryption and asymmetric encryption technology,analyzes its encryption,decryption mechanism and communication model,and gives full play to the advantages of the two,so that high efficiency encryption and decryption can be achieved in the transmission and storange room,and the data security can be guaranteed.
