Abstract

The invention provides a secure communication method and system of a mobile terminal. The method comprises a key negotiation process, a secure instant messaging process and a secure call process. Thekey negotiation process comprises the following steps: a first mobile terminal and a service platform obtain a first session key after identity authentication and key negotiation; a second mobile terminal performs identity authentication and key negotiation with the service platform to obtain a second session key; in the safe instant messaging process, the first mobile terminal encrypts and decrypts instant messaging information by adopting the first session key and the second session key between the service platform and the second mobile terminal; in the secure call process, the first mobileterminal uses the first session key, the second session key and the second mobile terminal to distribute a data encryption key through the service platform; and the first mobile terminal and the second mobile terminal encrypt and decrypt voice call information through the data encryption key.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method and system for secure communication of a mobile terminal. Background technique [0002] With the development of mobile networks and the improvement and popularization of the performance of smart terminals, the number of users of smart terminals and wireless communication and mobile applications has increased sharply, and the functional services based on mobile networks are also increasing. In particular, the information interaction function based on the wireless mode has inherent advantages, and has gradually affected people's life patterns, forming a new way of information interaction and communication. [0003] At the same time, due to the openness and flexibility of the smart terminal itself and the characteristics of the wireless network, data is easily monitored, intercepted, stolen or tampered with, causing certain security risks and losses to user dat...
