The application discloses a network security defense method, device, equipment, system and medium, and belongs to the field of data processing. The method comprises the following steps: obtaining original traffic data packets of a real business system; performing session recombination according to the original traffic data packets to obtain a session flow; performing structural analysis on the original traffic data packets, changing field values of at least part of fields obtained through analysis to obtain target data pairs comprising fields and field values; generating at least one honeypot decoy traffic data based on the session flow and the target data pairs; and running the at least one honeypot decoy traffic data on a decoy server and a decoy client. According to the embodiment of the application, the identification difficulty of the honeypot decoy and the real business system can be improved, so that the attractiveness of the honeypot decoy to attackers is improved.

This utility model relates to the field of missile aerodynamics and structural technology, and in particular to a missile wing deployment device. It includes a wing housing, with adapter shafts rotatably connected to both sides of the wing housing. Each adapter shaft has a wing deployment rocker arm, and each wing deployment rocker arm has a folding wing on the side closest to the wing housing. A servo motor is located under the adapter shaft. It is mainly used for the rapid deployment of missile wings, folding them when the missile is in a negative phase of flight and deploying them when it is in an active phase, fully utilizing the advantages of the wings. In the deployed state, the missile's aerodynamic shape changes significantly, and its flight trajectory deviates considerably, making it harder for air defense systems to predict and intercept during penetration.

The utility model discloses an interactive toy. The interactive toy comprises a shell; the shifting structure is rotationally arranged on the shell, and the shifting structure is provided with a driving part; the rotary drum structure is rotationally arranged on the shell, and the rotary drum structure is provided with a pattern display part and a driven part; the reset structure is arranged between the shifting structure and the shell; when driving force is applied to the shifting structure, the shifting structure rotates in the first direction, and the driving part is matched with the driven part to drive the rotary drum structure to rotate; and when the driving force to the shifting structure is cancelled, the shifting structure is driven by the reset structure to rotate in the opposite direction of the first direction, and the driving part and the driven part are separated from each other, so that the rotary drum structure rotates randomly. According to the utility model, the driving part is separated from the driven part by arranging the resetting structure, so that the rotating drum structure can rotate randomly after the driving force to the shifting structure is cancelled, the pattern change is unpredictable, and the interestingness and playability of the toy are obviously increased.

The invention discloses a data verification method and system based on a Hash algorithm, and the method comprises the steps: firstly building an access behavior baseline model for a target data object, recording an integrity proof chain of verification history, then intelligently starting a verification process through periodicity, during access or a predictive trigger mechanism based on risk assessment, and during verification, intelligently starting a verification process through an integrity proof chain of the verification history; the system dynamically generates a hash factor according to the current context and the check strategy hierarchy assigned for the data object, constructs a Merkle tree by using a hash algorithm corresponding to the hierarchy in combination with the data content, generates a current integrity signature, compares the signature with the newest historical signature in the proof chain, automatically starts a self-healing process if the signature is inconsistent with the newest historical signature in the proof chain, and does not start the self-healing process if the signature is not consistent with the newest historical signature in the proof chain. According to the process, the damaged data blocks can be accurately positioned and repaired from the redundant copies. According to the method, the problems that existing data verification is static and passive, the risk cannot be sensed, and the automatic repair capability is lacked are solved, and the intelligence, the safety and the system toughness of data integrity guarantee are remarkably improved.
