Internet-of-Things equipment and fog node authentication system and method

Abstract

The invention belongs to the technical field of fog computing, and discloses an Internet-of-Things equipment and fog node authentication system and method, and the Internet-of-Things equipment and fog node authentication system is composed of a fog layer and an equipment layer. the fog layer is composed of a plurality of fog nodes, the fog nodes are deployed near the Internet-of-Things equipment, one fog node communicates with one or more Internet-of-Things equipment, and each piece of Internet-of-Things equipment only belongs to a communication range covered by a certain fog node; a physical unclonable function (PUF) is embedded in each piece of Internet-of-Things equipment; the Internet-of-Things equipment and the fog node transmit data in a wireless communication mode; the Internet-of-Things equipment and fog node authentication method comprises the following steps: a trusted registration center registers for Internet-of-Things equipment; and performing security authentication between the Internet-of-Things equipment and the fog node. The Internet-of-Things equipment equipment and fog node authentication system provided by the invention has low delay, security and high efficiency, and is suitable for mutual authentication and secure communication between the Internet-of-Things equipment and the fog node.

Description

Technical field [0001] The present invention belongs to the field of fog calculation, and more particularly to an Internet of Things equipment and a fog node authentication system and method. Background technique [0002] At present, fog calculation is a new distributed calculation paradigm that extends cloud computing to the edge of the network, which provides calculations, network, and storage for the Internet of Things devices. Fog calculations not only extend cloud-based services to large geographical distribution. The introduction of fog calculation solves the latency problems in the cloud computing, so that the fog calculation can effectively provide a wide variety of applications for the rapid increase in networking equipment. In the fog computing environment, the fog node is deployed in an accessory of the Internet of Things equipment. The data collected by the Internet of Things equipment needs to be processed by wirelessly transmitting the fog node, which requires an ef...

AI Technical Summary

Problems solved by technology

[0005] (1) The current authentication scheme cannot well meet the requirements of low latency and lightweight

[0006] (2) The current authentication scheme is not robust, it is easy to be destroyed or captured by attackers, and the captured fog nodes will leak sensitive information

[0007] (3) The current authentication scheme uses complex cryptographic primitives, which are not suitable for resource-constrained IoT devices to participate in authentication

Authentication is the foundation of security, and a fog computing environment without security guarantees will lose its purpose of introduction
