Henon map image encryption algorithm



or subtraction operation mode combined with the method, making the crackers can not effectively get chaotic sequence. This compared to only using XOR encryption method of the image,[عزيزي الزائر يتوجب عليك التسجيل لمشاهدة الرابط للتسجيل اضغط هنا], the more secure,[عزيزي الزائر يتوجب عليك التسجيل لمشاهدة الرابط للتسجيل اضغط هنا], less likely to crack. 3 Experimental results and analysis of this algorithm to encrypt Lena map, take the second-order Henon map in the parameter a 0.2, £ 1, a 10; initial value (key)-zo = 1.00001121, z] a 1.20012020; another given a set of experimental values ​​37. A 1.00001121, z a 1.20012O21. Figure 3 (a) the original image, (b) for the use of encryption keys after the image, (c) with the experimental value for the decrypted image when, (d) under the correct key to decrypt the image. The results from this experiment, we can see, the initial value in the chaotic sequence can lead to very subtle differences in the image decryption failure. This is the initial value by the chaotic sequence of very high sensitivity characteristics of the decision, the initial value of bias arises when two completely different chaotic sequences; chaotic sequence in order to avoid problems arising from the correlation,[عزيزي الزائر يتوجب عليك التسجيل لمشاهدة الرابط للتسجيل اضغط هنا], we take Chaos in the data after 1000 iterations. 4 results based on ******** in the proposed new Henon map image encryption algorithm, in previous studies on the basis of one-dimensional Logistic evolved. Henon chaotic sequence generated by the Logistic chaotic sequence has a higher than complexity, thereby increasing the reliability of image encryption and security, increased difficulty to decrypt the image, the image encryption has played a very good effect. From the theoretical analysis to the simulation can be seen that this approach is feasible, Nang ● (a) original image {b) as an encryption (c) the error keys image (d) decrypted image encryption and decryption of images Figure3Imageencryptionanddecryption Figure 3 and with Henon map, we also proposed XOR and modular arithmetic combination of methods, compared to the previous encrypted image pixels only XOR algorithm, this combination of algorithms to improve the image encryption complexity, but also proved by experiments that the new algorithm has a higher security,[عزيزي الزائر يتوجب عليك التسجيل لمشاهدة الرابط للتسجيل اضغط هنا], image processing has a good prospect.
