Abstract

The present invention proposes a mobile terminal secure communication method and system, the method includes a key negotiation process, a secure instant communication process and a secure call process; the key negotiation process: the first mobile terminal and the service platform perform identity authentication and key The first session key is obtained after negotiation; the second mobile terminal obtains the second session key after identity authentication and key negotiation with the service platform; the secure instant messaging process: the first mobile terminal communicates with the service platform through the service platform The second mobile terminal uses the first session key and the second session key to perform encryption and decryption processing of instant messaging information; the secure call process: the first mobile terminal uses the service platform to The first session key, the second session key and the second mobile terminal distribute the data encryption key; the first mobile terminal and the second mobile terminal use the data encryption key to Encryption and decryption of voice call information.

Description

Technical field [0001] The present invention relates to the field of information security, and more particularly to a secure communication method and system of a mobile terminal. Background technique [0002] With the development of mobile networks and the promotion of intelligent terminal performance, intelligent terminals and wireless communications, mobile applications have increased dramatically, and mobile network-based function services are also increasingly enhanced. In particular, the information interaction function based on wireless mode has a congenital advantage, which has gradually influenced people's living mode, forming a new information interaction, communication mode. [0003] At the same time, due to the openness, flexibility, and wireless networks of the intelligent terminal itself, data is easily listened, intercept, stealing or tampering, resulting in certain security hazards and losses to user data. At present, the security threat caused by the user in the m...
