Abstract

The invention provides an encryption communication method of a mobile terminal. The method comprises steps as follows: a key management center distributes a key for a sending end and a receiving end; the sending end encrypts a signal sent by the key and sending the encrypted signal to the receiving end; after receiving the signal, the receiving end decrypts the signal through the key to restore the signal. The invention further provides an encryption communication system of the mobile terminal. The system comprises the mobile terminal, an encryption communication device and the key management center. The encryption communication method and system of the mobile terminal can guarantee end-to-end encryption transmission of data in a mobile communication system and the safety is high.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and system for encrypted communication of a mobile terminal. Background technique [0002] With the rapid development and popularization of mobile communication, mobile communication terminals, such as mobile phones, have become an indispensable tool in people's daily work and life. People are communicating directly and accurately through the voice and text message functions in mobile phones, but the transmitted information may involve sensitive information. Once the content of these calls or text messages is intercepted and eavesdropped by an illegal third party, it will cause serious damage. as a result of. [0003] Although the mobile communication system itself provides a set of security encryption functions, it is controlled by the operator, and the data is only encrypted during the wireless transmission of the air interface, but it is transmitted in plain te...
