Robust Hybrid Cryptographic Method for Cloud Computing Information Security

Future cloud computing will include virtualization, dynamic resource pools, and high availability. Without requiring computer users to get involved, cloud computing offers a solution to common computing issues including resource availability, software, and hardware. The following are the two main difficulties facing cloud computing first is deployment of cloud security over the internet and second is data storage. The data stored in cloud storage can be encrypted using a variety of cryptographic techniques. There are several issues with the existing algorithms, so this work has used the idea of MD5, Blowfish, and RSA algorithms. Furthermore, the proposed hybrid model has used the existing technique and provides the solution. The information is encrypted via the RSA algorithm, which is a modified version of the RSA algorithm. This work has used two different algorithms Communication of Encryption and Decrypt (CED) and Hybrid Data Encryption and Decryption process in Server (HD-EDS). Both algorithms have used the symmetric encryption algorithm which is called the RSA algorithm. The HD-EDS algorithm is a proposed hybrid algorithm that has included the RSA, MD5, and Blowfish properties of the algorithm. When data is uploaded to the cloud, it is encrypted using the RSA and Blowfish encryption techniques. This work has calculated the retrieval time between existing techniques versus the proposed hybrid technique and achieved 9.8 (ms) time. Another is the comparison between RSA, MD5, Blowfish, and HD-EDS achieved 40 (ms) which is less than MD5 and Blowfish algorithm. With their private key, the cloud controller may decrypt the data. Lastly, by contrasting the outcomes of our suggested hybrid approach with those of the current procedures, we have finished the performance evaluation.
