Description
Technical Field
The invention relates to an anti-interference attitude control method for a spacecraft with a measurement and control link under replay attack, which can solve the problem of high-precision and high-reliability control of an attitude system with a spacecraft measurement and control link under replay attack in an interference environment.
Background
With the development of aerospace technology, more and more precise aerospace missions require a spacecraft attitude control system to have higher control precision. However, on one hand, due to the complex space environment, the spacecraft is interfered by external environments such as solar radiation torque, gravity gradient torque, magnetic interference torque and the like, and the interference torque can cause the attitude of the spacecraft to generate disturbance; on the other hand, as the outer space gradually becomes the highest strategic point of maintaining national security and vital interests of countries in the world, the space countermeasure has become an important strategic means of the country, the spacecraft is used as a main attack object in the space countermeasure, and a measurement and control link between the spacecraft and the ground system is easily attacked by replay of enemies, so that the ground system receives wrong measurement information, the ground system makes wrong control decisions, and the task of the spacecraft fails and even crashes. The attack process of the replay attack is mainly divided into three steps, wherein in the first step, the historical value of the past measurement information is recorded by using a network monitoring method; secondly, capturing and erasing the current measurement information; and thirdly, replacing the current value of the measurement information with the historical value of the measurement information. Therefore, the method for controlling the anti-interference attitude of the spacecraft under the replay attack has important significance.
The maximum error detection in the conventional false information detection technology is widely applied to a static model system. Both chinese patent application No. 201310237995.9 and chinese patent application No. 201410059572.7 employ a filter residual-chi-square detection method to detect the maximum error. However, when an attacker has some a priori knowledge of the structure of the system, the attacker can inject deviations in a specific direction into the system and does not cause a change in the error. Similarly, if the attacker plays back the historical value of the measurement information to my party, under certain conditions, the error does not change, and the system cannot detect the attack. The chinese patent application No. 201510652179.3 proposes a satellite navigation forwarding type spoofing attack defense method and apparatus, but the forwarding type spoofing attack is different from the replay attack, the forwarding type spoofing attack injects a history value of measurement information to our party, but does not erase a real signal, the patent selects a signal emitting a world maximum signal as a real signal, and in the replay attack, an enemy not only plays back the history value of the measurement information to our party, but also erases the real measurement information, so that the system cannot obtain the real measurement information; the Chinese patent application number 201010042089.X provides a replay attack prevention system for an industrial wireless network, but a third-party detection module is introduced into the system, so that the complexity of a control system is increased, and the rapidity of the control system is influenced. In summary, the existing method cannot solve the problem of control of a system under a replay attack in an interference environment, and high-precision and high-reliability control of the attitude of the spacecraft is achieved.
