Embodiment 1

[0040] figure 1 A flow chart of a method for exchanging weather navigation data is shown. The method can be applied to a data service provider, such as a Web application server located on a ship. The method for exchanging weather navigation data provided in this embodiment is as follows: figure 1 shown, including steps S101 to S104:

[0041] Step S101: Receive a weather navigation data subscription request and an authorization code sent by a target data application terminal client. The authorization code is generated by the application system of the data application terminal manufacturer using the public key to encrypt the private key of the data application terminal, and the private key of the data application terminal is the data application terminal device obtained by the data application terminal manufacturer when issuing the data application terminal. unique hardware code.

[0042] In some cases, the private key of the data application terminal is the unique hardware co...

Embodiment 2

[0063] figure 2 Another method for exchanging weather navigation data is shown. The method can be applied to a data application terminal. The method for exchanging weather navigation data provided in this embodiment includes steps S201 to S203:

[0064] Step S201 , sending a weather navigation data subscription request and an authorization code provided by the data application terminal manufacturer to the data service provider. The authorization code is generated by the application system of the data application terminal manufacturer using the public key to encrypt the private key of the data application terminal, and the private key of the data application terminal is the data application terminal device obtained by the data application terminal manufacturer when issuing the data application terminal. unique hardware code.

[0065] Step S202, importing the target weather navigation data pushed by the data service provider.

[0066] Step S203 , decrypt the target weather na...

Embodiment 3

[0069] This embodiment provides a weather navigation data information service system, including:

[0070] Weather navigation data server, used to provide weather navigation data;

[0071] The web application server communicates with the weather navigation data server, and is used for executing the method for exchanging weather navigation data in the first embodiment.

[0072] In practical applications, the weather navigation data server is located on the shore, and the Web application server is located on the ship. The weather navigation data exchange method in the foregoing embodiment can realize the safe exchange of weather navigation data between ships and shores.

[0073] image 3 It is an example of the weather navigation data information service system. The roles in the weather navigation data information service process are defined as follows: According to the needs of ship weather navigation, the objects involved in the weather navigation data exchange process include...

Abstract

The invention provides a meteorological navigation data exchange method and system, a storage medium and a terminal, and the method comprises the steps: receiving a meteorological navigation data subscription request and an authorization code sent by a target data application terminal client, the authorization code being generated by encrypting a private key of a data application terminal by an application system of a data application terminal manufacturer through employing a public key; querying target meteorological navigation data corresponding to the meteorological navigation data subscription request; a unique serial number and a public key of a data application terminal manufacturer are utilized to decrypt the authorization code to obtain a private key, and the unique serial number and the public key of the data application terminal manufacturer are distributed by a data manager; and encrypting the target meteorological navigation data by using the private key, and pushing the encrypted target meteorological navigation data to a target meteorological navigation data application terminal client. The method can effectively solve the problem of ship-shore safety exchange of the marine meteorological navigation data, designs a ship-shore end-to-end encryption exchange mode of the meteorological navigation data, and effectively solves the problem of meteorological navigation data exchange safety.

Description

technical field [0001] The invention belongs to the fields of ocean engineering and shipping, and in particular relates to a method, system, storage medium and terminal for exchanging meteorological navigation data. Background technique [0002] Complex meteorological and sea conditions are an important factor affecting maritime navigation, maritime operations, and maritime military operations. In recent years, most of the ship navigation safety accidents at sea are due to the lack of accurate grasp of meteorological and sea conditions. Therefore, meteorological and sea state forecast information is of great significance to all activities at sea. [0003] With the rapid development of modern science and information technology, comprehensive marine meteorological and hydrological acquisition, analysis and forecasting capabilities have initially formed in the world, such as comprehensive detection, accurate forecasting and disaster warning of marine meteorology and hydrology. ...
