This paper presents an image encryption instead of text to observe the block cipher modes of operation of the complex AES processing. A platform is built based on the mode operations for the experiments. The cipher image of ECB may appear patterns due to the identical color inputs. CTR and MCTR make those identical inputs different by adding counters to remove the patterns while CBC, CBF, and OBF do it by adding serious Cipher function outputs which are almost random numbers. The mode features resulted from adding number series and the ways of addition, are discussed and compared, which help to design the Switching Control to configure all the modes into a platform for the AES mode operations and image test.
