Cloud computing has revolutionized the ability to store and analyze vast quantities of data in a manner that is both economical and adaptable. Keyword search is an important mechanism for users to retrieve information from the cloud, but traditional keyword search techniques are vulnerable to attacks from cloud service providers or malicious users. The proposed mechanism uses a combination of encryption, data fragmentation, and user authentication to guarantee that only approved users can search for and retrieve the data, and user authentication is implemented. At the same time, the data remains confidential and secure. The results present a prototype implementation of the mechanism and evaluate its performance in a real-time scenario.
