Problems solved by technology

[0004] However, the deeper security and system performance issues in the above security mechanism have not been fully considered, and there is a lack of corresponding key management system
The following problems exist in the indefinite use of the encryption key: 1. The longer the key is used, the greater the chance of it being leaked; 2. If the key has been leaked, the longer the key is used, the greater the loss; 3. The key The longer it is used, the greater the temptation for people to spend energy to decipher it; 4. It is generally easier to cryptanalyze multiple ciphertexts encrypted with the same key
The greater the value and data transfer rate, the more frequent key changes are used

Abstract

The invention discloses a key management method of an Internet of Things (IOT) sensor system. The method comprises the following steps of: A. performing the registration of sensor nodes and the authentication of sensor nodes by a gateway. B. starting a key management module, using the preset secret information in the sensor nodes and the gateway, and generating key pairs and network keys of the gateway between the sensor nodes and the gateway according to the different security requirements of packets, and updating the key pairs and network keys periodically. The method supports the update of different keys in different periods of validity, and provides effective security protection for the keys for the gateway and the sensor network communication under the gateway.

Description

technical field [0001] The invention relates to the technical field of Internet of Things security, in particular to a key management method for an Internet of Things sensor system. Background technique [0002] Sensor networks are widely used in the fields of urban public safety and home smart security. Different sensor networks gather information from various types of sensors (infrared sensors, door magnetic sensors, combustible gas sensors, smoke sensors, etc.), and use the comprehensive resources of the Internet to provide services for monitoring and security management. Under the realistic demands of severe urban public safety, establishing an efficient sensor security mechanism can not only solve prominent practical problems, but also is an important guarantee for promoting the development of the Internet of Things. [0003] The current relatively mature ZigBee security mechanism is provided by the security service provider layer. A shared security key is used. The ...
