Description
Technical Field
The invention relates to the technical field of data transmission methods, in particular to a safe offshore data transmission method.
Background
In the prior art, the internet is generally used for transmitting and setting safety information, the marine data transmission method is easy to be hijacked or tampered by someone with great interest, once the data is hijacked or tampered, the marine running ship cannot obtain correct management information, and safety accidents are easy to cause.
Disclosure of Invention
In order to solve the problems, the invention provides a safe marine data transmission method which has high safety and can not cause data to be tampered or hijacked.
The technical scheme of the invention is as follows: a safe marine data transmission method comprises an information sending module for sending data, an information receiving module for receiving the data, an encryption processing module for encrypting the data, a decryption processing module for decrypting the data and a data transmission network for connecting the information sending module and the information receiving module, wherein the data transmission network comprises a Beidou communication network and the Internet, the transmission data comprises secret key data and ciphertext data, the secret key data is transmitted to the information receiving module from the information sending module through the Beidou communication network, and the ciphertext data is transmitted to the information receiving module from the information sending module through the Internet.
By adopting the technical scheme, when marine data transmission is required, firstly, the encryption processing module generates key data, then the encryption processing module encrypts original information to generate ciphertext data, and as the information amount which can be transmitted by the Beidou communication network at one time is small, the key data is suitable for being transmitted by the Beidou communication network, and as the key data and the ciphertext data are transmitted by the Beidou communication network and the Internet respectively, the Beidou communication network has extremely high security, the phenomenon of information hijacking or falsification basically cannot occur, even if the ciphertext data transmitted by the Internet is hijacked or falsified, correct information cannot be obtained, and potential safety hazards cannot be generated, so that the security of marine data transmission is greatly improved by the data transmission method.
The invention further comprises the following steps: the encryption processing module encrypts the original information according to the key data and encrypts the original information into ciphertext data, and the decryption data decrypts the ciphertext data according to the key data.
The invention is further provided that the key data is randomly generated by the encryption processing module.
By adopting the technical scheme, the encryption processing module encrypts the original information into ciphertext data according to the key data, and the decryption data decrypts the ciphertext data according to the key data, so that the original information can be decrypted only by simultaneously acquiring the ciphertext data and the key data, the key data cannot be tampered when being sent through the Beidou communication network, and the safety of marine data transmission is greatly improved.

Detailed Description
As shown in fig. 1, a safe marine data transmission method includes an information sending module for sending data, an information receiving module for receiving data, an encryption processing module for encrypting data, a decryption processing module for decrypting data, and a data transmission network for connecting the information sending module and the information receiving module, where the data transmission network includes a beidou communication network and the internet, the transmission data includes key data and ciphertext data, the key data is transmitted from the information sending module to the information receiving module through the beidou communication network, and the ciphertext data is transmitted from the information sending module to the information receiving module through the internet.
When marine data transmission is needed, firstly, a key data is generated through the encryption processing module, then the encryption processing module encrypts original information to generate ciphertext data, the Beidou communication network has small information amount capable of being transmitted at one time, the key data is suitable for being transmitted through the Beidou communication network, the key data and the ciphertext data are transmitted through the Beidou communication network and the Internet respectively, the Beidou communication network is extremely high in safety, the phenomenon that the information is hijacked or tampered basically cannot occur, even if the ciphertext data transmitted through the Internet is hijacked or tampered, correct information cannot be obtained, potential safety hazards cannot be generated, and the safety of marine data transmission is greatly improved through the data transmission method.
The encryption processing module encrypts the original information according to the key data and encrypts the original information into ciphertext data, and the decryption data decrypts the ciphertext data according to the key data.
The key data is randomly generated by an encryption processing module.
Because the encryption processing module encrypts the original information into ciphertext data according to the key data, and the decryption data decrypts the ciphertext data according to the key data, the original information can be decrypted only by simultaneously acquiring the ciphertext data and the key data, and the key data can not be tampered when being sent through the Beidou communication network, so that the safety of marine data transmission is greatly improved.
