Embodiment

[0080] Such as Figure 1-2 As shown, in this embodiment, a short message encryption communication method based on dynamic time stamp and national secret algorithm is provided, which is used for communication between the master station and the slave station.

[0081] In the invention, there is only one master station, and there may be one or more slave stations.

[0082] The short message encryption communication method provided by the present invention, as a supplement to the communication encryption method, ensures the reliability and safety of information transmission. Through the way of dynamic time stamps, a communication relationship with a solid heartbeat detection is established between the master station and the slave station. Even if the communication content between the master station and the slave station is intercepted by hackers, the master station and the slave station can pass the timestamp Identification to determine whether the information is still the source...

Abstract

The invention discloses a short message encryption communication method based on a dynamic timestamp and a national secret algorithm. Based on an existing timestamp concept and a Beidou short message communication technology, a monitoring mechanism is self-defined to send a piece of information to a master station so as to ensure that communication between the master station and a slave station is in an online state. An sm2 encryption algorithm is used to ensure that communication data between an upper computer and a lower computer is not intercepted and is safer and more reliable; the slave station ID is distributed to the slave station by using the master station in an equipment authentication mode, so that unique identification and intercommunication of communication information between the master station and the slave station are realized, dynamic encryption is realized in future encryption technology application, and the reliability is higher.

Description

technical field [0001] The invention relates to an encrypted communication method, in particular to a short message encrypted communication method based on a dynamic time stamp and a national secret algorithm. Background technique [0002] The Beidou satellite navigation system has short message communication capability of Radio Determination Satellite Service (RDSS). Beidou RDSS has the characteristics of monitoring and broadcasting, etc. RDSS short messages can be used to carry data and realize data communication. [0003] With the long-term practice and application of Beidou short message technology in the fields of industry, agriculture, and navigation, the technology is becoming mature. At the same time, with the deepening of Internet technology and encryption technology, people are increasingly aware of the importance of information confidentiality. Information confidentiality is not only of great significance in the commercial field, but also plays a pivotal role in ...
