Data Security and Privacy Issues in Cloud Environment

Cloud Computing is a computing paradigm where the user store data, access data, and deliver services through the internet, many people are opting for the cloud for storing the data which makes working on things easier and also reduces the maintenance of the hardware. Security and privacy are two of the cloud computing industry’s most difficult issues. There are more chances of cloud servers being hacked, which give access to data to an unauthorized user, and the data can contain sensitive information which is why many users, or many organizations hesitate to migrate to the cloud. To protect and provide security to the data, one should apply some encryption techniques to the data before transferring them to the cloud. For providing security many cryptographic techniques are used, some of the encryption techniques are Data Encryption Standard, Advanced Encryption Standard, Rivest-Shamir-Adleman, and Attribute-based. The primary goal of adopting encryption techniques is to give security to the data in the cloud, which is enhanced by using an encryption algorithm. This study compares the different encryption techniques along with their advantages and drawbacks
