Hybrid Cryptographic Algorithm Using Multiprocessing for File Storage on the Cloud

Abstract

Every aspect of our modern life is interconnected to the internet leading to the creation of massive volumes of data that we cannot store on our smartphones or other storage devices owing to their size. An effective way to store enormous amounts of is using cloud storage technology, usage of these services has been rising quickly lately. Many businesses are switching from conventional storage techniques to cloud storage as it makes it simple to access information for users whenever and anywhere needed. Different cryptographic methods are used to safeguard the data. This paper proposes a hybrid cryptographic algorithm that utilizes the AES (Advanced Encryption Standard) algorithm and the Blowfish algorithm. Our proposed cryptographic algorithm has higher speeds for executing encryption and decryption processes. This rate increase is achieved by implementing multiprocessing in their execution. Results demonstrate that our hybrid approach has faster execution times and greater throughput.
