| Abstract: | The power consumption curves were often affected by plenty of noise in real environment attack.In order to improve the efficiency of the attack,this paper analyses characteristics of several common filtering noise methods and completes experiments to the specific questions.At last,it compares the filtering effects and draws a conclusion that moving average filter is the most suitable method to solve this kind of problem. |
