A secure communication method and system based on a secure communication module

Abstract

The present invention proposes a secure communication method and system based on a secure communication module. The secure communication method includes: the secure mobile terminal obtains the session key after key negotiation with the security gateway of the cloud platform through the secure communication module, and performs Encrypted transmission of policy files; the security communication module configures firewall policies according to the policy files; when accessing Internet applications: the terminal application sends data for accessing the Internet to the security communication module for policy matching; if the first policy match is successful, the security communication The module sends the data accessing the Internet to the Internet application for networking processing; when accessing the cloud platform service: the secure communication module configures the gateway IP and listening port according to the policy file; sends the business data accessing the cloud platform to the security The communication module performs policy matching with the second policy file; thereby ensuring that the secure mobile terminal safely accesses the Internet application or the cloud platform through the secure communication module.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a secure communication method and system based on a secure communication module. 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. Especially with the gradual application of Internet of Things technology, mobile terminals usually need to remotely access the cloud platform to control smart devices and other operations. For example, users can remotely access the cloud platform through mobile terminals to control and manage smart homes and smart door locks. operate. [0003] However, when users remotely access the cloud platform and access the Internet through mobile terminals, they are us...
