Secure communication method and system based on secure communication module

Abstract

The invention provides a secure communication method and system based on a secure communication module, and the method comprises the steps that a secure mobile terminal obtains a session key after carrying out the key negotiation with a security gateway of a cloud platform through the secure communication module, and carries out the encryption transmission of a strategy file; the security communication module performs firewall policy configuration according to the policy file; when the internet application is accessed, the terminal application sends data for accessing the internet to the safety communication module for strategy matching; if the first strategy is successfully matched, the security communication module sends the data of accessing the Internet to the Internet application fornetworking processing; when the cloud platform service is accessed, the security communication module performs gateway IP and monitoring port configuration according to the strategy file, and sends the service data accessing the cloud platform to the security communication module to perform policy matching and the like with a second policy file. And thus, the secure mobile terminal is ensured to securely access 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...
