Abstract

The encryption of RGB colour image using microcontroller ATMEGA 32 is studied in the present paper via synchro- nization with one-dimensional chaotic map. Two microcontrollers are used to execute encryption and decryption algo- rithms under synchronized condition to demonstrate the cryptosystem. Both the microcontrollers run the dimensional logistic map and they become synchronized through open plus closed loop (OPCL) coupling. Under synchronized con- dition, the stored data of the input image in one microcontroller is encrypted with its generated chaotic sequences and transmitted to the remaining microcontroller, known as the receiver. The receiver microcontroller decrypts the encrypted data and stores in its memory. After decryption of the full image data it is forwarded to LCD display to visualize the decrypted image. The strength of security of the algorithm is analyzed by a number of cryptanalysis techniques like, correlation coefficient, histogram analysis, information entropy, NPCR, UACI, MAE, etc. 1 Introduction academic and industrial world.
