Enhancement of Data Security for Cloud Computing with Cryptography Techniques

In cloud computing, users may access their crucial data that is kept on distant servers over the Internet. The amount of sensitive and important data is expanding quickly as technology develops every day. Data security is crucial in cloud computing because cloud computing involves storing and processing data on remote servers, often belonging to third-party providers. This means that data is transmitted and stored outside of the user’s immediate control, making it more vulnerable to security breaches and cyberattacks. A security breach of user data highlights the importance of user privacy. Every form of data has a varied level of protection requirements. In this paper, we have suggested a model that categorizes the data in accordance with its security characteristics. We have created a new hybrid approach to achieve this. We have built a hybrid algorithm using AES and DES. The performance of the hybrid system is compared to the current hybrid technology, showing that the recommended approach offers excellent security and confidentiality of user data. The shortcomings of both symmetric and asymmetric encryptions are solved by hybrid cryptography and steganography.
