In this paper we implement by microcontroller ATMEGA16a a new synchronization scheme of the 2D chaotic Henon map and Personal Identification Number (PIN) encryption and decryption method. Two different systems are taken in two different positions: one is the driver microcontroller and the second is the driven microcontroller for these synchronization purposes. Two chaotic maps at parameter mismatch condition are synchronized by Open-Plus-Closed-Loop (OPCL) coupling scheme and used in a secure PIN transaction. The proposed technique is simulated and hardware circuit is implemented successfully.
