Things-internet gateway system based on virtual machine and data interactive method

Abstract

The invention discloses a things-internet gateway system based on a virtual machine and a data interactive method, which mainly solves the safety integration problem of a things-internet user network and a service provision network. In the system, a virtual machine monitor is built on a hardware layer of the gateway, and a safety virtual machine and a service virtual machine are arranged on the virtual machine monitor, so as to separate different functional modules. The safety virtual machine comprises a secret key management module, an authentication module, an encryption and decryption module, an information processing module and a judgment module; the service virtual machine comprises a multi-network interface module, a user management module, an information management module, a perception node management module and an information publishing module; restricted data is transmitted among the virtual machines by a safety data channel in the virtual machine monitor, the safety virtual machine has no external interface, and users only can access the service virtual machine; in the invention, the safety of the things-internet gateway is improved, security protocol integration difficulty among different networks in the things internet is reduced, and the system is suitable for integration of different networks in the things internet.

Description

technical field [0001] The invention belongs to the field of communication technology, and relates to the design and use of a gateway structure in the Internet of Things, specifically an Internet of Things fusion gateway system based on virtual machine technology and a method for using it, which is applied to the communication and security fields of fusion between different networks in the Internet of Things . Background technique [0002] The concept of "Internet of Things" is a network concept that extends and expands its client terminal to any item and item for information exchange and communication on the basis of the concept of the Internet. Among them, the wireless sensor network, RFID network, etc. are used as the terminal sensing network, interconnected with the existing Internet network or wireless communication network, and connect the actual items with the Internet through corresponding protocols for information exchange and communication. A network structure conc...

AI Technical Summary

Problems solved by technology

If the user's service usage and the security information and security process in the gateway cannot be effectively separated, the gateway is likely to be subject to malicious attacks aimed at this

Moreover, due to the different security protocols between different networks in the Internet of Things, it is difficult to integrate different security protocols.

At the same time, if the conversion process of security protocols cannot be completed on a secure gateway structure, the security of these security protocols may be greatly reduced.
