Sourabh Singh , Anurag Jain. "An Enhanced Text to Image Encryption Technique using RGB Substitution and AES". International Journal of Engineering Trends and Technology (IJETT). V4(5):2108-2112 May 2013. ISSN:2231-5381. published by seventh sense research group.


In network security applications, before transmitting data to a remote machine it is encrypted at the sender side using any standard encryption algorithm. Most of the encryption algorithms make use of secret key without which it becomes very difficult to retrieve the actual data In this paper we propose a method which at first transforms the text into an image using an RGB substitution, and then encrypts the resulting image using AES Algorithm, under this approach, the secret key is smartly sent along with the cipher text in a single transmission, thus it also solves th e key exchange problem that generally arises in most of the encryption models. The encryption and decryption process make the use of a combination database for text to image transformation. This paper is divided into following four sections; in section - I, we presented basic introduction of Network Security, in section - II, a survey on related algorithms has been presented, section - III discusses the proposed model and section IV concludes the paper.
