  7. Abstract:
  8. For authenticity and confidentiality of data in design of smartcards, cryptographic algorithms are mainly used. These cryptographic algorithms are the base of secure communication, so they have been created to be resistant to theorical and mathematical analysis.
    However, Implementation of these algorithms in electronic systems and devices such as smartcards lead to leak of information. This leaked information, known as side channel, can be utilized to reveal secret characteristics of system. Apparently, power consumption of device is most important side channel and gained a lot of attention from designers and attackers.
    Hence, investigating methods of side channel attacks, practical issues related to them, and finding countermeasures for them play a critical role in the area of secure embedded system design.
    Implementation of side channel attacks on smartcards needs special tools and rules. The main goal of this thesis is to provide a set up for implementing such attacks on smartcards and prepare the essential tools (softwares and hardwares) for evaluating their vulnerability.
    In the next step different methods of power analysis would be introduced, and results of attacking two different smartcards would be discussed
