Side-Channel Attacks against ARIA on Active RFID Device

RFID is a technology for automated identification of objects 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 device. 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. Besides, 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.
