Security verification method and system for Beidou short message terminal

Abstract

The invention discloses a safety verification method for a Beidou short message terminal. The method comprises the following steps: acquiring an encrypted message sent by an application end; decrypting the encrypted information; judging whether decryption is successful or not: if yes, passing safety verification, determining that the application end is successfully connected with the Beidou short message terminal, sending a piece of encryption information to the application end to respond to successful connection, and storing the ID information, obtained through decryption, of the application end in the Beidou short message terminal; if not, not passing safety verification, determining that the connection between the application end and the Beidou short message terminal fails, so the Beidou terminal equipment can be prevented from being maliciously used by a third party, and verifying, binding and perfecting the security of a Beidou communication link through the terminal equipment end. The invention further discloses a safety verification system of the Beidou short message terminal. According to the invention, the Beidou terminal equipment can be prevented from being maliciously used by a third party, and the security of a Beidou communication link is improved through verification and binding of the terminal equipment end.

Description

technical field [0001] The invention relates to the field of map making, in particular to a method and system for safety verification of a Beidou short message terminal. Background technique [0002] The Beidou satellite navigation system is a global satellite navigation system developed by our country. In addition to positioning, navigation, and timing functions, it also has the function of two-way short message communication. Users can send short message information of 40-60 Chinese characters at a time to sail in the ocean. has important application value. In uninhabited areas or areas without signal coverage, due to environmental restrictions, personnel need to seek help and communicate with outsiders. Beidou short message communication can be applied to this special scenario. [0003] The Beidou short message standard protocol does not define the so-called security authentication specification, and more of it belongs to a communication format requirement specification....

AI Technical Summary

Problems solved by technology

As long as any application can connect to Beidou terminal equipment through Bluetooth (or serial port), it can use Beidou equipment, and can send short messages according to the requirements of the communication protocol. Therefore, it may be maliciously used by a third party, thereby posing a security risk
