Abstract |
|
Permutation is a commonly used primitive in multimedia (image/video) encryption schemes, and many permutation-only algorithms have been proposed in recent years for protection of multimedia data. In permutation only image ciphers, the entries of the image matrix are scrambled using a permutation mapping matrix which is built by a pseudo-random number generator (PRNG). The literature on the cryptanalysis of image ciphers indicates that permutation-only image ciphers are insecure against ciphertext-only attacks and/or known/chosen plaintext attacks. In our proposed work we intend to develop the cipher data by considering two encryption algorithm concerning Arnold Cap Map (ACM) and Chaotic sequential data. In this work we intend to improve the PSNR value of the image. |
