Nowadays, data sharing and storage is one of the most frequent activities associated with cloud computing. Since cloud computing handles large-scale user data at a time, sometimes it contains confidential information or data of the user that needs additional security so that the user can store the information in the cloud storage over the un-trusted computing network. In this regard, cloud data security becomes the primary need for storing confidential information or data over the cloud. The symmetric encryption approach is considered one of the best cryptography techniques to secure cloud data. It provides more security to the cloud information or data than other techniques. This research paper proposes a hybrid symmetric encryption technique to offer additional security to the user's data stored in the cloud compared to the single symmetric encryption approach. The investigated techniques show high processing speed and secure data sharing over the cloud with others. In addition, the computation time associated with the encryption and decryption is also minimized even when multiple users access the same file over the cloud. The proposed method aims to improve the privacy policy by investigating new algorithms for extra cloud data security. There is a broad scope of cryptography techniques in cloud computing, not only for securing the cloud data but also for solving various security and privacy issues while dealing with confidential data.
