Repository and Retrieval of Data using AES Security in Cloud Computing Environment

Abstract: The use of the internet is continuously expanding. People exchange vast amount of digital data every day. Some information is critical and must be protected from unauthorised access. Encryption methods are critical for preventing unauthorised access to original data. To encrypt data, a variety of algorithms can be utilised. The Advanced Encryption Standard (AES) algorithm, which is extensively supported and used, is one of the most efficient algorithms available. The goal of this work is to demonstrate how to create secure file transfer using AES encryption and decryption techniques in a cloud environment. Hackers can intercept files as they are being sent from the source to the destination. If files are not wrapped, they can be easily exploited. Thus, AES algorithm is used to safeguard file transfer networks. If AES is employed in file sharing systems, it is claimed to dissuade thieves from attempting to steal data when sending files. According to the study's findings, AES offers more protection during data encryption and decryption during file transfers without interruption from hackers attempting to steal data intentionally.
