智能电网广域监控系统的时间戳攻击
Time Stamp Attack on Wide Area Monitoring System in Smart Grid
摘要：
安全成为智能电网中一个极其重要的问题。为了保证智能电网的稳定运行，必须在电网中广泛配置大量的测量设备。以往的研究主要集中在对智能电网系统的虚假数据注入攻击。在实际应用中，由于电网数据通信系统不容易被入侵，虚假数据注入攻击不易实现。在本文中，我们证明了一种新的时间戳攻击是一种实用的和危险的智能电网攻击方案。由于大多数测量设备都配备了全球定位系统（GPS）来提供测量的时间信息，因此通过欺骗GPS来攻击测量系统的可能性很大。通过北美电网的实测数据进行仿真，验证了时间戳攻击对智能电网的有效性。
英文摘要：
Security becomes an extremely important issue in smart grid. To maintain the steady operation for smart power grid, massive measurement devices must be allocated widely among the power grid. Previous studies are focused on false data injection attack to the smart grid system. In practice, false data injection attack is not easy to implement, since it is not easy to hack the power grid data communication system. In this paper, we demonstrate that a novel time stamp attack is a practical and dangerous attack scheme for smart grid. Since most of measurement devices are equipped with global positioning system (GPS) to provide the time information of measurements, it is highly probable to attack the measurement system by spoofing the GPS. By employing the real measurement data in North American Power Grid, simulation results demonstrate the effectiveness of the time stamp attack on smart grid.
