Comparative Analysis of AES and RSA Algorithm for Cloud File Transfer

Abstract

Cloud computing improvements have resulted in information being contracted by cloud services. Dropbox and Google Drive are cloud storage services that provide users low-cost storage. We provide a way of protecting files by encrypting and decrypting them, which provides an enhanced level of security. We use the Double encryption approach to encrypt the files that we upload to the cloud. The file is encrypted twice, one after the other, using the two algorithms. The file is encrypted using the AES method first, followed by the RSA algorithm. During the algorithm's execution, the corresponding keys are created. This strategy raises the level of security. The parameters covered here include security level, speed, data confidentiality, data integrity, and cypher text size. Our method is more efficient as it satisfies all the parameters where the conventional methods failed to do so. Drop Box is the cloud service we utilized to store the file's content, which is encrypted using the AES and RSA algorithms
