In different cases of data transmission in a communication system of clouds the most widely used approach is encryption which is considered by far a necessary step. Encryption in simple words is locking of information in a box which needs a key to unlock; now it all depends upon the type of technique and its necessary awareness becomes a mandatory part of complete communication systems. Cryptography involves a 5-tuple (P, K, C, and E, D) consisting of the plain text or message P, set of keys K, cipher text C, encryption algorithm E and decryption algorithm D. An Original message is known as the plaintext, while the coded message is called the cipher text. The process of converting from plaintext to cipher text is known as enciphering or encryption; restoring the plaintext from the cipher text is deciphering or decryption. The many scheme used for encryption constitute the area of study known as cryptography. To ensure information and data privacy over the cloud, application is encrypting the user data before sending it over the cloud. In our research work we propose a new scheme which encrypts the text or image message in decrypt form by executing some steps. We expect that results of this technique are very fruitful as compared other technique.
