Nowadays, it is widely recognized that data security will play a central role in the design of IT devices. There are more than billion wireless users by now; it faces a growing need for security of embedded applications.
This thesis focuses on the basic concept; properties and performance of symmetric and asymmetric cryptosystems. In this thesis, different encryption and decryption algorithms have been implemented on embedded systems. Moreover, the execution time and power consumption of each cryptography method have been evaluated as key performance indicators. CAESAR and AES are implemented for the microcontroller (ATmega8515). The STK 500 board is used for programming of the ATmega8515. Furthermore it is used for the communication between the microcontroller and PC to obtain the performance advantages of the cryptography methods. Time and power consumption are measured by using an oscilloscope and a multimeter. Furthermore the performance of different cryptography methods are compared.
