Abstract

With the development of the wide implementation of cryptography and crypto chip,the attacks targeting at the crypto chips is increasing. Differential power analysis( DPA) attack is a popular side canal attack method. Through the power trace analysis the DPA attacker can analyze the right key out, not depending on known the details of the crypto algorithm. So the research on DPA attack is essential. In this paper,a smart card system based on DPA analysis is realized. In order to design the security measures against this attack,the energy traces from the DPA attacks are optimized for more accurate data.
