Abstract: Cloud Computing (CC)is the delivery of on-demand shared computing resources to computer or other devices, CC has changed the way we think about the way we perform our day to day operation and now a day’s almost all applications are using CC to meet their requirements without actually licensing or purchasing the software and also the infrastructure. There is a lot of chance to misuse of data by the third party (Cloud Service Provider) and the main security factors which affect the performance of the system are confidentiality, availability and integrity of data. Many encryption algorithms have been developed and implemented to provide security for the data which is stored in the cloud, but no algorithm provides 100% security for the data which is stored in the cloud. This paper gives a study of different encryption techniques used in CC that is used to provide security for the data stored in the cloud.
