3results about How to "Reduce vulnerability" patented technology

The utility model is suitable for metal processing equipment technical field provides a kind of mechanism of cover steel seal stamping lock catch, mechanism includes rack, stamping drive arrangement, detachable punch assembly, swing arm, push rod, fixture, pull rod and tension spring etc., and stamping drive arrangement includes motor, belt pulley, belt and the cam structure consisting of cam and bearing.Its working principle is: motor drives belt pulley and cam rotation by belt, bearing on cam drives swing arm swing by connecting rod, swing arm drives push rod and steel seal die to complete stamping action, reset is realized through tension spring simultaneously, and automation processing is realized by cooperation material conveying platform.The mechanism positioning is accurate, impact force is controllable, and degree of automation is high, and it can adapt to different specifications workpieces, effectively improve processing efficiency, and reduce production cost.

The application discloses an electric propeller, an aircraft and a cluster control method, relates to the technical field of aircrafts, and discloses the electric propeller, which comprises a propelling main body, a capturing mechanism and a propelling device, the propelling main body comprises gas inlets and ion outlets arranged at two ends of the propelling main body, the gas inlets are communicated with the external environment to supply gas into the propelling main body, and the ion outlets are communicated with the external environment; the capturing mechanism is arranged in the propelling main body and close to one side of the gas inlets, and can capture gas in a rarefied atmosphere; the propelling device is arranged in the propelling main body and close to one side of the ion outlets and is communicated with the capturing mechanism, can ionize the gas captured by the capturing mechanism to obtain environmental gas ions, and can discharge the environmental gas ions after acceleration from the ion outlets, so that a large amount of propellants carried with the aircraft is not needed, long-term tasks can be completed, and the application range is wider. The aircraft disclosed by the application can reduce the launch mass and cost of the aircraft, and the cluster control method can reduce the vulnerability of the aircraft system.

This application provides a zero-trust gateway data access method, client, gateway, communication system, storage medium, and computer program product. The method is applied to a client and includes: sending a single-packet authorization request message to the zero-trust gateway; receiving a single-packet authorization response message including ciphertext of a first key factor; decrypting the first key factor using a first private key; sending the first authentication information and the second key factor ciphertext to the zero-trust gateway, so that the zero-trust gateway generates a session key based on the first and second key factors using a preset algorithm; simultaneously, the client also generates a session key based on the first and second key factors using a preset algorithm; and establishing a connection channel with the zero-trust gateway based on the session key. This application uses a zero-trust gateway, which offers high security; and the data packet structure is designed with privacy in mind, resulting in fewer vulnerabilities and a lower risk of attack.
