| Abstract | ||
| Encryption using chaotic schemes provides a greater level of security than conventional ciphers. In this paper, we present an encryption system uses chaotic sequences for digital image encryption depends on two chaotic systems. The first chaotic system that is used to select the pixel position to be encrypted, while the second system is used to generate a key to change the value of the selected pixel using XOR logic operation .The paper proposes an approach to change the pixels values different from the traditional approach in the sense that instead of changing the values of the pixels serially starting from the first pixel ,it selects the pixels randomly and change their values with random number, which gives more immunity and security. The results show that the proposed system works successfully when tested.Ialso shows that it has very high sensitivity to parameters change where a change of 0.0001% in one out of 12 parameters does not allow successful decryption. | ||
