Information security transmission method and system

Abstract

The invention discloses an information security transmission method and system, and belongs to the technical field of communication security. The method comprises the steps that S1, generating a firstsecret key via a cloud service platform; S2, storing the private key, and sending the public key to the corresponding security gateway; S3, writing the public key into the state secret chip; S4, generating a second secret key, and encrypting the second secret key by using the public key; S5, transmitting the encrypted second secret key to the cloud service platform; S6, decrypting through the private key to obtain a second secret key, and storing the second secret key; S7, performing encryption and decryption operation through the second secret key; the system comprises a first receiving module, a generation module, a storage module, a first sending module, an encryption and decryption module, a second receiving module, a write-in module and a second sending module. The method has the beneficial effects that the encryption algorithm is ensured to be autonomous and controllable, the certification authority is authoritative and credible, the security and reliability of information transmission are improved, and the communication security is ensured.

Description

technical field [0001] The present invention relates to the technical field of communication security, in particular to an information security transmission method and system. Background technique [0002] With the rapid development of the Internet and Internet of Things technology, smart homes have emerged as the times require. Smart homes use Internet of Things technology to integrate various devices in the home (such as audio and video equipment, lighting systems, curtain control, air conditioning control, security systems, digital cinema systems, etc.) , audio-visual server, shadow cabinet system, network appliances, etc.) are connected together to provide home appliance control, lighting control, telephone remote control, indoor and outdoor remote control, anti-theft alarm, environmental monitoring, HVAC control, infrared forwarding and programmable timing control, etc. functions and means. Compared with ordinary homes, smart homes not only have traditional residential...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, the smart home has the following technical defects in communication security authentication: first, the home gateway communicates with the cloud server in plain text, which will pose a serious threat to the security of the smart home; second, it uses non-national secret low-intensity The security of the software encryption algorithm cannot be guaranteed, it is not self-controllable, and there is no guarantee that there will be no backdoor; the third is that the existing traditional encryption method only uses one key for each terminal or only selects the key in a limited space. The key is easy to be cracked; Fourth, all smart home manufacturers have built their own certification systems, lacking authoritative organizations to provide reliable identity certification services, and user security has to rely entirely on the integrity of manufacturers
