The fast adoption of cloud storage in enterprise and personal computing has raised a lot of issues related to data confidentiality and security. As the number of data breaches and unauthorized access cases continues to increase, one of the most important priorities has become the need to ensure the safety of confidential information. One of the most essential answers to this problem is encryption, which provides a strong system of protecting the data even in the case of the cloud infrastructure being attacked. This paper provides a comparative study of the common encryption algorithms with emphasis on the effectiveness of the algorithms in ensuring confidentiality in cloud storage systems. The evaluation of key performance indicators such as encryption and decryption speed, key length, security strength, resource consumption (computational), and scalability was carried out systematically. As a result of this analysis, the research concludes that Advanced Encryption Standard is a recommended option when it comes to applications that require high speed and low latency of data processing. On the other hand, Elliptic Curve encryption is highly efficient on a resource-constrained system, i.e., a processing- and memory-constrained environment, and therefore, can be applied in mobile and edge computing. The normal algorithm, like Rivest-Shamir-Adleman, is secure, but it has been proven to be resource-consuming and cannot be used in dynamic cloud processes. The paper has come to the conclusion that the choice of an encryption method should be determined by the specific operational context and security requirements of the intended cloud deployment.
