摘要
Abstract
For the power value being cleared and its address mutation problems of the operating smart electricity meters, an analysis method based on fault injection is presented. The rapidly changing pulse interference signals are added into the I2C bus of the E2PROM. The signal enters the E2PROM chip along the SDA and SCL pin. The fault site reappears. The experiment result shows that when some incidents happen, the anti-interference ability of RAM and E2PROM chips are different. The data on the I2C bus will mutate when the disturbance reaches a certain level. The meter is initialized due to the software design defect and the data mutate.关键词
