All of a users devices such as tablets, laptops, mobile phones, desktop PCs and other technology gadgets can be used to store and access files stored on the cloud. How cloud storage works is that it stores the users confidential files on the storage servers, and users have the freedom of accessing their files from any location. The ability to access files from remote locations using just a stable internet connection gives cloud an edge over other storage options. Hence more and more people are shifting towards the more convenient option of cloud for storing their data. Hence cloud storage provides a way to access ones personal data across all of ones personal devices. On the users personal usage front, many users nowadays have multiple devices, such as one or more mobile/cell phones, tabs, laptops, desktop PCs et cetera. The reason for this is that, on the business front, global expansion of companies require data to be shared amongst employees for collaborative working. Traditional storage devices such as flash drives, hard disks and other kinds of physical storage devices are slowly becoming obsolete. Keywords Cloud Computing and Storage AES Algorithm RSA Algorithm Blowfish Algorithm. The system also uses two different hybrid approaches for encryption and decryption, namely AES and RSA algorithms, and AES and Blowfish algorithms, and shows a comparative study on the difference between the two approaches.
#Encrypted file storage download
The user can then download their files from the cloud through the portal, which results in the decrypted (or original) file getting downloaded to their local computer. In this system, the user uploads a file to the portal, it gets encrypted and then uploaded onto the cloud. Hence even if a security breach were to take place, the attacker would get access to encrypted data, which would still ensure data confidentiality. This paper presents a review of a system which stores data on the cloud after encrypting it. Hence data security is a very important component of cloud storage. But with cloud storage comes security risks and data leak possibilities. This is where Cloud Computing and Storage comes into the picture. This has brought the need to make access to data from any location possible and feasible. Furthermore, companies are expanding globally and opening offices at various locations across the globe.
