Embodiment

[0025] In this example, the method for encrypting dynamic and static messages and anti-counterfeiting identification codes is to use the RC2 block encryption algorithm.

[0026] First, set the same key in the law enforcement monitoring management center and the AIS ship-borne equipment of each law enforcement ship, and determine the application identification number and anti-counterfeiting identification code in the stealth mode, and then set the AIS ship-borne equipment of each law enforcement ship to provide normal mode And the switching function of the stealth mode, when the AIS shipboard equipment of the law enforcement ship is in the normal mode, it will normally send the normal message message corresponding to the model of the AIS shipboard equipment, when the AIS shipboard equipment of the law enforcement ship is in the stealth mode , to determine whether the ground speed of the law enforcement ship is greater than 2 knots, and if so, the dynamic and static messages and ...

Abstract

The invention relates to an information technology. In order to solve the problem that the existing law enforcement ship can not be managed by a law enforcement monitoring and managing center when the law enforcement ship is invisible, the invention provides a ship invisibility and management method. The technical scheme can be summed up as follows: when the law enforcement ship is invisible, thedynamic message information of the law enforcement ship is packed into the application data area of No.8 information after being encrypted, and the source MMSI (maritime mobile service identify) of the No.8 information is filled with random numbers; and other law enforcement ships and the law enforcement monitoring and managing center can resolve the No.8 information by a secret key. The invention has the beneficial effect that in the invisible mode, the law enforcement ship is invisible to common ships but can obtain the dynamic and static information of the common ships; and other law enforcement ships and the law enforcement monitoring and managing center still can obtain the position data of the law enforcement ship. The method is suitable for the law enforcement ship and the law enforcement monitoring and managing center.

Description

technical field [0001] The invention relates to information technology, in particular to the technology of AIS ship-borne equipment. Background technique [0002] At present, in the fields of maritime affairs, fishery administration, maritime anti-smuggling, anti-narcotics, anti-smuggling, and anti-terrorism, more and more AIS (Automatic Identify System) shipboard equipment is used to help law enforcement Personnel find and track suspicious target ships. However, ordinary AIS shipboard equipment is like a double-edged sword. In the process of helping law enforcement ships discover and track suspicious target ships, it also exposes its own relevant information, thus making illegal ships Measures can be taken in advance to avoid the inspection of law enforcement ships. The traditional stealth method is to let law enforcement ships adopt radio silence and only receive AIS information but not send it. This is not a good way. First, law enforcement ships cannot see each other. I...
