A method for continuous authentication in the Internet of Things

Abstract

The invention discloses a method for continuous authentication in the Internet of Things. The Internet of Things terminal device defines a time according to the number of information packets to be continuously sent, and adds it to the request data packet and sends it to the gateway. The request data generates a temporary authentication information. The gateway uses the temporary authentication information for verification within a predetermined time range. The terminal device will add temporary authentication information to each message sent to the gateway within the validity period of the session. There is no need to perform complex public / private key authentication operations, which realizes the concept of continuous authentication, which is of great significance for improving resource consumption due to complex message transmission authentication in IoT environments. At the same time, due to the constraint of timeliness, the temporary authentication information is only valid within the validity period of the session, which reduces the potential security risks caused by using long-term preservation of valid authentication in most systems.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a method for continuous authentication in the Internet of Things. Background technique [0002] In recent years, the Internet of Things has developed rapidly and received attention in both academia and industry. By connecting sensors, tiny smart devices and smart home appliances through the Internet of Things, the Internet of Things provides a new form of "communication" for people and devices, making the virtual information world seamlessly connected with the real world. IoT applications may involve environmental monitoring, e-health, electric vehicles, and smart homes. As many IoT devices as possible can be used in users' daily lives, privacy and security issues are very important. IoT devices are characterized by limited memory and storage capacity and low computing power, and these limited resources limit the functions that IoT devices can achieve. Therefore,...
