Cloud Computing Network Security Technology Based on Big Data Analysis

Abstract

AbstractAs a new network model, Internet big data cloud computing technology can integrate excellent computing practices in the Internet, significantly improve the efficiency of big data computing, and make full use of network resources. The development of network technology has reached a new height, and the significance and role of network data security has also been widely valued. Based on this, this paper begins to study the application of cloud computing network security technology in big data analysis. Based on this, this paper studies the cloud computing network security technology under the big data analysis. In this paper, literature analysis and statistical analysis are selected to study. In these studies, by collecting a large number of relevant information, it has laid a solid theoretical basis for the in-depth study of this paper. This paper takes the network and data security in cloud computing environment as a key research topic. According to the characteristics of cloud computing, this paper introduces the related concepts and definitions of cloud computing, and the current research results in the field of cloud computing network and cloud computing security. In view of the dynamic data operation and the integrity and consistency verification of data files in cloud computing environment, this paper introduces the concept and definition of cloud computing, this word proposes a verifiability experiment based on Merkle hash tree technology to support data dynamic operation, and proposes an access control experiment based on attribute encryption algorithm for data file access control in cloud computing environment. The results show that the hierarchical Merkle hash tree construction experiment in this paper has obvious advantages over other experiments in terms of time cost. The attribute based encryption algorithm can minimize the generation of key and the times of encrypting plaintext and decrypting ciphertext, and can effectively improve the permission change rate of massive users sharing data files in cloud computing environment.KeywordsBig dataCloud computingNetwork security technology
