The invention relates to a turnover and end control semi-physical simulation test method, which comprises the following steps of: designing corresponding control logic according to control requirements of different stages of an aircraft; in the initial launching stage, inertial smoothing is carried out on a course angle, a pitch angle, a course sight angle and a pitch sight angle; in the terminal guidance stage, exponential smooth transition processing is carried out on the roll angle according to a certain rule according to the missile-target distance; and in a tail end attack stage, according to the course sight angle and the pitching sight angle variation, the course sight angle and the pitching sight angle are re-assigned so as to control the course sight angle and the pitching sight angle of the five-axis turntable. According to the invention, the problem that the aircraft cannot be subjected to turnover maneuvering and end attack simulation due to limitation of rolling frames of the ...

The invention relates to an information deletion and verification method and system based on information overwriting. The method at least comprises the steps that a deletion request and random number seed information are received; performing fine-grained overwriting operation on the information in a random overwriting mode; in response to the extraction request of the state information after the information is deleted, the master node of the information source domain broadcasts the extraction request of the state information after the information is deleted to at least one slave node; and sending the state information and related verification parameters after the information fed back by the slave node is deleted to a verification terminal, so that the verification terminal verifies the overwritten content based on the verifiable pseudo-random function. According to the method and the device, the problem of information logic deletion recoverability is effectively solved, the verifiability ...
