Abstract: To analyze the power consumption of cryptographic processor software and improve the performance to resist power attack，a method called instruction-based processor power modeling is proposed.The constructing of power model，the method to get instruction power and power measurement platform are expatiated.Based on the previous work，the power of AES encryption algorithm software adapting to an application specific crypto processor is simulated and the result is compared with the measured power data.The analysis result indicates this kind of processor power modeling method is available.
