Abstract

In Wireless networks, the security of data and information has important role in digital communication and multimedia communication. Different types of encryption algorithms have an important role to provide the security to the wireless networks. Cryptography basically used for the data confidentiality and privacy by making indiscernible. Hence the original data cannot be interrupted by the unauthenticated user. The encryption techniques and different types of useful algorithms are used to provide the more security to the applications. In this paper the well- known method chaotic algorithm is used. Chaotic algorithm is used in real time secure image transmission systems. This algorithm is very popular method used in Research for encryption and decryption process. The combination of chaotic theory and cryptography has an very important role in Information Security. In this communication, a new image encryption algorithm based on chaotic map is proposed for gray scale 2D image. In this proposed algorithm, the plain or original image is taken which has MXN dimension. Then Redistribute the pixel pair wise by deciding the parameters for relocating which is only known to the authenticated owner. Using this process all pixels are scrambled in entire image with the help of iteratively to optimize the scattering of energy.
