Several modifications and analysis on encryption performance and security were studied and evaluated by several researchers to measure the efficiency and quality of the proposed enhancement in the encryption method. In this paper, the authors evaluated the performance of the image encryption using the enhanced RC6 permutation-diffusion operation integrating the concept of cyclic-shift permutation. Statistical analysis, key space analysis, and runtime execution analysis were conducted based on considered metrics such as key sensitiveness, histogram and maximum deviation, mean squared error, mean value analysis and the speed measurement of encryption and decryption process. Based on the numerical and visual results, the good qualities of encryption using this method were achieved.
