Secure Data Transfer using Compression, Encryption algorithm in the Cloud Environment

Abstract

Escorted in the increasing evolution in the cloud computing field, several people establish the cloud in the absence of knowing the guaranteed strategies and procedures which can cause considerable threat. Securing data in the cloud becomes a challenging task. Although encryption and compression algorithms could be utilized to provide reliability, everyone has problems. The encryption complication is that the data could be lost. The compression complication is that there transmission errors. As claimed to the effort in this article, a integrated approach for information integrity has been suggested utilizing encryption along with  compression algorithms to upgrade the reliability of the data. Predominately, the RC4 algorithm has been utilized to cipher the confidential message. Furthermore, the ciphered message has been compressed utilizing LZ78. Thirdly the compressed output has been converted into a scrambled image and uploaded in the cloud environment. Therefore three ranges of reliability have been issued using the suggested approach. The encryption and compression algorithms suggest a structured repository to attain personal evidence and integrity authentication with the nominal process, time complexity and repository area.

Keywords: Cloud Environment, LZ78 Algorithm, Rivest Cipher4, Scrambled image.
