Problems solved by technology

In the field of the Internet of Things, compared with the Internet, the devices that require access to the Internet will have exponential growth. It is conceivable that this method will cause great trouble to users: the user needs to enter the key every time the device is connected to the network, and the user experience is very unfriendly
[0005] 2) The key is easily cracked
[0007] 3) Risk of information copy forgery
The disadvantage of this method is that the two sides of the communication carry out the calculation of the key required for communication by presetting some secret information in the node and the gateway, whic

Embodiment 1

[0040] The workflow of the slave machine includes two main processes: initialization process and communication process.

[0041] The initialization process is that after the slave is powered on, it is connected to the master through a secure connection to initialize various parameters required for the subsequent communication process, mainly including device identification, public key and static private key. Participating modules include: registration authentication management module, random number generation module and secure connection communication module.

[0042] The communication process is divided into two parts: the wireless connection establishment process and the dynamic key communication process. During the establishment of wireless communication, the slave sends a connection application and waits for the host to confirm. After the host confirms, the slave obtains the current dynamic private key, and then enters the dynamic encryption communication link. The partic...

Embodiment 2

[0069] The workflow of the host includes two main processes: the initialization process and the communication process.

[0070] The initialization process is the public key initialization process after the master is powered on, and through a secure connection with the slave, it is used to initialize various parameters required for the subsequent communication process, mainly including device identification, public key and static private key. Participating modules include: registration authentication management module, random number generation module and secure connection communication module.

[0071] The communication process is divided into two parts: the wireless connection establishment process and the dynamic key communication process. During the establishment of wireless communication, the host computer confirms the connection application of the slave computer, passes the current dynamic private key to the slave computer, and then enters the dynamic encryption communicat...

Embodiment 3

[0096] image 3 It is a schematic diagram of the device structure of the slave device in the network security key protection method provided by Embodiment 3 of the present invention. The slave device is mainly composed of six modules: a random number generation module, a registration authentication management module, a secure communication module, and a wireless transceiver Module, data packet encryption and decryption module and wireless communication module. Wherein, the registration authentication management module is connected with the random number generation module, the secure communication module and the wireless transceiver module; the wireless transceiver module is connected with the data packet encryption and decryption module; the data packet encryption and decryption module is also connected with the wireless communication module. The functions of each module are as follows:

Abstract

The invention discloses a network security key protecting method in the field of Internet of things. The network security key protecting method comprises the following steps: a public key is randomly generated after a host computer starts up a work; the host computer and a slave computer complete connection initialization through a reliable connection way; equipment identifiers of counterparts are mutually recorded by the host computer and the slave computer, and a static private key during connection establishment is generated under the domination of the slave computer; after accessing to the network, all communications between the host computer and the slave computer have a dynamic encryption mechanism dominated by the host computer. Through application of a safe connection initializing mechanism and a dynamic key mechanism, network connection between the host computer and the slave computer can be quickly and securely realized, so that a user does not need to remember a security key, but secure wireless connection can be quickly and conveniently established; the risk that the key is monitored by a malicious device and the risk that information is copied and faked are avoided.

Description

technical field [0001] The invention relates to the technical field of Internet of Things security, in particular to a key protection method and a wireless access device of an Internet of Things sensor system. Background technique [0002] The development of the Internet has promoted the sharing of information, but while information sharing has brought great convenience to human beings, it has also brought about problems in information security. As a result, people have introduced a key-controlled information encryption mechanism to ensure information security (unauthorized personnel without a key cannot decrypt encrypted information). The traditional key system has some defects of its own. In the field of Internet of Things, such problems will become more prominent, mainly reflected in the following three aspects: [0003] 1) Unfriendly user experience [0004] The traditional key mechanism requires users to enter when joining the network, thus preventing unauthorized p...
