A Multi-Layered Framework for Enhancing Data Security in Cloud Storage Using Authentication, Encryption, and Integrity Verification

Cloud computing has recently played an increasingly important role in the information technology (IT) industry due to its enhanced performance, wide accessibility, low cost, and many other benefits. It provides vast data storage and faster processing for various users over the Internet. Data security in the cloud remains a major ongoing challenge that limits the widespread deployment of cloud computing. The problem addressed in this research is how to enhance data storage security in cloud computing through multiple methods to provide trustworthy and secure cloud data storage services. This study proposes a framework for data security designed to protect data through a combination of double authentication for appropriate data classification and encryption, as well as digital signature verification to ensure data integrity during transmission and retrieval. he Message Authentication Code ensures data integrity during transmission. The proposed framework integrates various techniques and specialized procedures to protect data end-to-end, from the data owner to the cloud and ultimately to the user. The framework employs triple-layer authentication to ensure secure access at all stages: by the user the data owner and the cloud service.
