Abstract: Small embedded devices such as microcontrollers have been widely used for identification, authentication, securing and storing confidential information. In all these applications, the security and privacy of the microcontrollers are of crucial importance. To provide strong security to protect data, these devices depend on cryptographic algorithms to ensure confidentiality and integrity of data. Moreover, many algorithms have been proposed, with each one having its strength and weaknesses. This paper presents the implementation of Advanced Encryption Standard(AES) running inside a PIC16F877A microcontroller
