KeyGen:performed by the data owner to randomlygenerate a public/master-secret key pair (pk,msk).
FileUpload: It encrypts the File withConvergent Encryption applying 256-bit Blowfish algorithmwhere the convergent key is from MD-5 Hashing of the fileand before uploading the file in to the cloud server, server will be perform duplicate check with help of hashing of the file.
Key-Encryption:To preventing lose of Convergent Encryption Data Owner will encrypt the
Convergent key with public-key pk,and send the master-secret key to Users.
FileDownload:Data Users can access the file which is shared by Data Owner. Here User can …show more content…
