Cloud computing is an environment that enables its users to store data in virtualized storage. Cloud provides different services to users; the prime aim of this service usage is to store data in the cloud. When the users store data in the cloud, security of the data is becoming the topmost challenge to be considered in the cloud environment. There are different approaches and techniques which are proposed to address the security of data in the cloud. This paper presents a study and review of different security algorithms that are used in the cloud to secure the cloud environment. The paper presents the comparison of security algorithms with respect to different parameters. Findings and observations obtained from the study of different security algorithms are discussed. Finally, the paper suggests some points to be considered at the time of developing security algorithms for the cloud environment.
