Abstract

Web-based Cloud Computing is widely used to store data. Most firms who are shifting to clouds find it cost-effective. Despite its popularity, it has presented several security concerns to its users. Cloud Computing data security has become a critical issue that requires prompt response. This paper proposes an appropriate usage of AES and an effective cloud-based data storage solution. The proposed data security solution is implemented by improving the standard AES algorithm. Furthermore, the proposed techniques use de-duplication to save storage space for user data. The Extensive Advanced Encryption Standard (EAES) methodology was applied, and the results were superior to the conventional Advanced Encryption Standard method. The research tries to tackle the issues stated above in stages. Initially, a broad library of strategies addressing the problem of data security is explored, and their limitations are noted. The Extensive Advanced Encryption normal technology is used, yielding considerable results as compared to the normal Advanced Encryption Standard approach.
