Massive IoT device authentication method, storage medium, and information data processing terminal

Abstract

The invention belongs to the technical field of Internet of Things security, and discloses a massive Internet of Things device authentication method, a storage medium, and an information data processing terminal. The massive Internet of Things device authentication method interacts between an IOT device and a smart city operation center IOC, and completes the device through a secure channel. Initialization; after the device initialization phase is completed, the aggregator AG is selected through the IOC for aggregator authentication; after the aggregator authentication is completed, the IOT device completes the group authentication with the assistance of the AG; after the group authentication is completed, the devices in the group complete the session encryption with the assistance of the AG key negotiation. The invention selects a device with a high trust value as an aggregator, assists the IOC to perform group certification for other devices, and makes the remote certification of a large number of IOT devices more reliable and efficient. At the same time, the present invention uses a reputation mechanism to monitor the trust value of the device, preventing devices that have successfully authenticated from being instigated by attackers to affect the entire system network.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things security, and in particular relates to a massive Internet of Things device authentication method, a storage medium, and an information data processing terminal. Background technique [0002] At present, with the popularization of 5G, the Internet of Things will also be fully developed and applied due to the increase in network communication speed. IOT devices have been widely used in the construction of smart cities. The "smartness" of smart cities is mainly reflected in intelligent perception, comprehensive interconnection, resource sharing, and collaborative cooperation. The identity verification of IOT devices is a major challenge to the security of smart cities. The attacker can maliciously place counterfeit devices, forge their identities and pretend to be legitimate devices to access the network, thereby illegally receiving and sending information. Attackers can also take advanta...

AI Technical Summary

Problems solved by technology

However, due to the huge number of IOT devices and numerous categories, there is still a lack of a unified security identification and identity authentication management mechanism

[0003] Identity authentication mechanism is an important tool to ensure the effectiveness of communication, but remote authentication of IOT devices with limited computing resources is vulnerable to insecure communication channels

Since the construction of smart cities needs to consider the remote authentication of massive IOT devices, the traditional certification scheme cannot be fully applied

In the traditional proof scheme, the user provides a set of credentials with proofs such as passwords or digital certificates. There are problems of relying on certificates and not being able to bind access requests to their sources, and most of them can only prove one-to-one or one verifier proves all Authenticators, so new solutions need to be put forward

[0004] Through the above analysis, the existing problems and defects of the existing technology are as follows: in the traditional certification scheme, the user provides a set of credentials with password or digital certificate and other proofs, and there are problems of relying on the certificate and not being able to bind the access request to its source. And most of them can only prove one-to-one or one verifier can prove all authenticators
