Problems solved by technology
However, 3G still does not provide an encryption mechanism for the terrestrial network, voice services are still transmitted in the form of plain voice, and 3G still has security risks
[0006] From the above analysis, we can see that there are many security problems in 2G and 3G communication. The mobile communication network itself does not provide end-to-end security measures for many services including voice services. Users, such as military government departments and commercial users, have increasingly urgent demands for secure data services on mobile networks

Embodiment Construction
[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented.
[0018] Bluetooth technology is an open global specification for wireless data and voice communication. It is based on low-cost short-range wireless communication and provides a special connection communication technology for the communication environment of fixed and mobile devices.
[0019] Data transmission is the basis for realizing data communication. In the past, wired connections were used for data transmission. In recent years, wired connections have gradually shown their own shortcomings, such as limited transmission distance, high cost, and difficult wiring. These fac...

The invention discloses a secure communication method and device. The method comprises: sending preset Bluetooth configuration information to a terminal after establishing a Bluetooth connection with the terminal, and receiving data sent by the terminal based on the Bluetooth configuration information; encrypting the received data to obtain the encrypted data and converting the encrypted data into first target data corresponding to a preset mobile communication mode, and sending the first target data to a base station which establishes a communication connection, such that the base station sends the first target data to a mobile switching center (MCS) of a core network and receives the feedback data from the MSC. As compared with the existing technology, the secure communication method and device provided by the invention acquire the data of the terminal through a Bluetooth wireless link and encrypt the acquired data for transmission to the base station, thus the security for data transmission is improved and the secure mobile communication is achieved.
Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a secure communication method and device. Background technique [0002] With the development of mobile communication technology, mobile communication security technology is also accompanied by the development from scratch. [0003] The first generation of mobile communication network: analog cellular mobile communication system (1G), the first generation of mobile system hardly adopts any security technology. [0004] The second generation of mobile communication network: digital cellular mobile communication system (2G), in order to solve the unsafe problems such as malicious eavesdropping and illegal access of 1G network, 2G adopts security technical measures such as user identity authentication, key distribution and data encryption. To a certain extent, the security communication of mobile users is guaranteed. Nevertheless, 2G still has some security risks. It o...
