RFID is a technology for automated identification of ob- jects and people. But, it is possible to leak much side channel information related to secret information when the tags and a reader run on system. Especially, an attacker get physical access to the chip or its field and perform so called side channel attacks like a DPA or a DPFA which make it possible to obtain a secret key stored on the de- vice. In this paper, we describe a modified power analysis and power frequency analysis attacks on Telos RFID device which side channel analysis is applied to ARIA algorithm with the Hamming weight of the intermediate results. Be- sides, we experiment the power analysis attacks on above device both the time and the frequency domain. Finally, we analyze the experimental results to find a cause that our methods are not applied to Telos module.
