Data Security of Cloud Computing

With the rapid development of cloud computing,data security and privacy protection become the crucial problems in the research of cloud computing. Based on the full lifecycle model of data,this paper proposes forwards data security and privacy protection framework,expounds the critical problems of data security and privacy protection in cloud computing environment,including retrieval of encrypted data,integrity validation and provable data possession,privacy protection and query privacy,and describes in detail the development,principle,significance of fully homomorphic encryption and its application in data security and privacy protection,thus pointing out a direction for future research.
