Abstract

Cloud computing is a large scale distributed computing paradigm in which a pool of computing resources is available to users via the Internet. Hence Security plays  an important role in cloud computing. The universal technique for providing confidentiality of transmitted data is cryptography. This paper provides a technique to encrypt the data using watermark and send the encrypted data through cloud to the requested user. For authentication the sender and receiver exchanges key between them. The key is approved by the owner then only the data accessed by the user. The Rubik’s Cube Encryption is used for the watermark encryption. The result shows better security than existing algorithms. This algorithm provides efficient transmission in heterogeneous computing environments.
