Cloud storage, in general, is a collection of Computer Technology resources provided to consumers over the internet on a leased basis. Cloud storage has several advantages, including simplicity, reliability, scalability, convergence, and cost savings. One of the most significant impediments to cloud computing's growth is security. This paper proposes a security approach based on cloud security. Cloud security now plays a critical part in everyone's life. Due to security concerns, data is shared between cloud service providers and other users. In order to protect the data from unwanted access, the Security Service Algorithm (SSA), which is called as MONcrypt is used to secure the information. This methodology is established on the obfuscation of data techniques. The MONcrypt SSA is a Security as a Service (SaaS) product. When compared to current obfuscation strategies, the proposed methodology offers a better efficiency and smart protection. In contrast to the current method, MONcrypt eliminates the different dimensions of information that are uploaded to cloud storage. The proposed approach not only preserves the data's secrecy but also decreases the size of the plaintext. The existing method does not reduce the size of data until it has been obfuscated. The findings show that the recommended MONcrypt offers optimal protection for the data stored in the cloud within the shortest amount of time. The proposed protocol ensures the confidentiality of the information while reducing the plaintext size. Current techniques should not reduce the size of evidence once it has been muddled. Based on the findings, it is clear that the proposed MONcrypt provides the highest level of protection in the shortest amount of time for rethought data. © 2022 Elsevier B.V., All rights reserved.
