In open network Encryption is used to transmit data securely. Each type of data has its own features, therefore to protect confidential image data from unauthorized access different techniques should be used. A framework is presented in this paper to evaluate image encryption schemes. A number of parameters such as correlation coefficient, information Entropy and a number of pixel change rate are used to quantify the security of encrypted images instead of visual inspection. Encryption efficiency analysis and security evaluation of some schemes like Zonal Transformation Matrix Method and Primitive Root Based Image Encryption schemes are presented. Experimental results demonstrate that the Zonal Transformation Matrix Method provides effective performance and security compared to primitive ischolar_main based encryption scheme.

With the fast development of data exchange in electronic system, safety of information is becoming more important in data storage and transmits. Because of commonly using images in industrial practice, it is very important to protect the confidential data from unauthorized access. This paper suggests that image encryption and decryption process based on block based encryption. The algorithms consider here are zonal based image encryption and primitive ischolar_main based image encryption. The zone based image encryption is working based on the principle of zonal transformation matrix, whereas primitive ischolar_main based image encryption is based on the principle of primitive ischolar_main theorem. The attribute considered for the comparative study are information entropy and average deviation analysis. Experimental results demonstrate that the zone based image encryption method provides effective performance compared to primitive ischolar_main based encryption method.
