Survey on Encryption Schemes used in Clouds
Cloud computing, is an emerging computer technology that provides users to remotely store their data in a server and provide services on-demand. Since remote data storage is here, data security and privacy is the most critical issues. Users can read, write and store data to cloud. To protect the confidentiality of the data stored, the data must be encrypted using some encryption algorithms. Attribute Based Encryption (ABE) method is a well-known encryption algorithm used to encrypt data stored in clouds. In this paper, the authors are going to analyze different variations of encryption schemes used to store data in cloud.
