Encrypted transmission method and encrypted transmission system for marine environment detection data

Abstract

The invention discloses an encrypted transmission method and encrypted transmission system for marine environment detection data. Encrypted transmission and decryption processing of the collected marine environment data plaintext are completed through one-time communication. An encryption end uses the marine environment data plaintext to generate a data ciphertext by adopting a symmetric encryption method, and the symmetric secret key are safely processed by adopting a digital signature and an asymmetric encryption mechanism. The data ciphertext and the symmetric secret key which are subjectedto safety processing are packaged into a communication data packet to be transmitted to a decryption end. After receiving the data, the decryption end firstly performs decryption and authentication processing on the symmetric secret key, and then decrypts the data ciphertext by the processed symmetric secret key. The data plaintext is restored. The method and system disclosed by the invention areused for safe communication of observation data of ocean sensors, and have small communication cost. The effects of safety, low power consumption and high efficiency of marine environment detection data transmission are guaranteed.

Description

technical field [0001] The invention relates to the field of information security, in particular to an encrypted transmission method and an encrypted transmission system for marine environment detection data. Background technique [0002] Marine environment detection data refers to the data collected by sensors deployed in ocean water bodies or along the coast. These data need to be transmitted to the data center on the shore through the communication network for storage, calculation, aggregation and analysis. The marine environmental observation data is confidential data, and in order to ensure the communication security of the data, encrypted transmission is required. Due to the limited energy of the sensor, and the energy consumption of data transmission and reception is the largest, the safe communication of marine environment detection data needs to minimize the communication traffic while ensuring safety. However, in the currently commonly used data encryption transmi...

Problems solved by technology

However, in the currently commonly used data encryption transmission method, the sending and receiving parties usually need to negotiate the encryption algorithm, key parameters, etc. through security associations before transmitting data, which adds a lot of additional communication burden, low communication efficiency, and is not suitable for marine environments.
