AbstractIn this paper, a new chaotic image encryption scheme is proposed, which uses the combination of stream cipher and block cipher to spread and then uses the Logistic mapping matrix to perform the block sort transformation to complete the confusion. The specific method is as follows: First, perform the triple XOR operation, non-linear S-box transformation and linear cyclic shift transformation on the key. Second, the triple XOR operation of the transformed key and the plaintext and Logistic mapping sequence are used to obtain the semi-ciphertext. And set the obtained semi-ciphertext and plaintext as key components of the next round of encryption. Finally, the transformation of sorting and partition of the Logistic mapping matrix are used to confuse the semi-ciphertext. The experimental results show that the proposed algorithm improves the encryption efficiency, has good security and can resist common attacks.

Difficult Issue

Absolute protection is a difficult issue to maintain the confidentiality of images through their transmission over open channels such as internet or networks and is a major concern in the media, so image Cryptography becomes an area of attraction and interest of research in the field of information security. The paper will offer proposed system that provides a special kinds of image Encryption image security, Cryptography using RSA algorithm for encrypted images by HEX function to extract HEX Code and using RSA public key algorithm, to generate cipher image text. This approach provides high security and it will be suitable for secured transmission of images over the networks or Internet.
