Efficient and Reliable Data Storage Security against Malicious Data Modification in Cloud Computing

Abstract

Cloud Computing becomes the next generation architecture of IT Enterprise. In contrast to traditional solutions, Cloud computing moves the application software and databases to the large data centers, where the management of the data and services may not be fully trustworthy. This unique feature, however, raises many new security challenges which have not been well understood. In cloud computing, both data and software are fully not contained on the user's computer; Data Security concerns arising because both user data and program are residing in Provider Premises. Clouds typically have single security architecture but have many customers with different demands. Every cloud provider solves this problem by encrypting the data by using encryption algorithms. This paper investigates the basic problem of cloud computing data security. We present the data security model of cloud computing based on the study of the cloud architecture. We improve data security model for cloud computing. In proposed system, we are going to make robust data storage security model in which group member’s data accessing scheme is used, for dynamic groups in the cloud. We analyze the security of our scheme with data confidentiality and demonstrate the efficiency of our scheme in experiments against malicious data modification.
