An Effective Differential Power Attack Method for Advanced Encryption Standard

In order to improve the efficiency of side-channel attack and reduce attack costs, an effective differential power analysis (DPA) method for advanced encryption standard (AES) is presented. By building the power acquisition platform based on current main stream EDA tools, a lot of power consumption traces can be achieved with ease. In addition, a critical distinguishing function is investigated so as to the key recovering can be more efficient and practical. Finally, two attacking experiments using our analytical method for AES are performed based on the developed DPA platform. Simulation results show that the key of the AES can be cracked correctly illustrating our analytical method has high effectiveness.
