Multi-factor-based industrial Internet of Things session key negotiation method

Abstract

The invention discloses a multi-factor-based industrial Internet of Things session key negotiation method which comprises the following steps that: a user stores personal information by using a smart card, communicates with intelligent equipment deployed in the industrial Internet of Things and Internet of Things nodes by connecting a mobile phone or other intelligent terminal equipment, acquires equipment state information in real time, and performs remote management and monitoring on the equipment. The method is based on the environment of the semi-trusted management center and more accords with reality, meanwhile, the pseudonym of the user is generated by the user and the server together, and the pseudonym of the user can be updated in real time after each key negotiation process, so that it is ensured that identity information of the user cannot be leaked, anonymity of the user is ensured, the non-linkability and the non-traceability are ensured, and the safety is improved. A key pre-distribution method is adopted, and based on a multi-factor authentication mode, namely biological characteristics, passwords and intelligent cards, main encryption operation is bit operation and a hash function, so that the calculation overhead and the communication overhead of a key negotiation scheme are reduced.

Description

technical field [0001] The invention belongs to the communication technology of the Industrial Internet of Things, and in particular relates to a session key agreement method of the Industrial Internet of Things based on multi-factors. Background technique [0002] The Internet of Things (IoT), or the Internet of Everything, refers to an expanded and expanded network based on the Internet. It consists of many information sensing devices, no matter where they are located, they can be remotely accessed and controlled anytime and anywhere via the Internet to realize the interconnection between users, machines and objects. The Industrial Internet of Things (IIoT) is one of the main applications of IoT. In the IoT environment, most IoT devices or nodes have the ability to process information and communication, and have addressable Internet Protocol addresses (IP addresses), but limited resources. For IoT devices in different IoT environments, users can access and control them t...

AI Technical Summary

Problems solved by technology

[0005] In most key agreement schemes, either the key agreement process is not lightweight enough to meet the needs of more resource-constrained devices or sensor nodes, or it cannot satisfy sufficient security in the IoT environment

In terms of functionality, most solutions cannot meet more ideal functional features, such as revoking users, dynamically adding devices, dynamically changing personal-related key information (including biometrics and passwords), etc.
