Authentication key protocol of block chain applied to edge of wireless sensor network

Abstract

The invention discloses an authentication key protocol of a block chain applied to the edge of a wireless sensor network, a wireless sensor is accessed to the network through a gateway node, the gateway node transmits data to an edge server, and the edge server is responsible for storing and calculating data generated by a large amount of Internet of Things equipment at an edge end; before entering an Internet of Things environment and starting to work, a trusted registration mechanism firstly registers a specific gateway node, an edge server, all wireless sensors subordinate to the specific gateway node and a user node closest to the specific gateway node; the registration comprises registration of a wireless sensor and a gateway node, registration of an edge server Leader node and registration of a client node, and then authentication and key negotiation are carried out. The requirement of lightweight application can be met; and an access control scheme suitable for the scene is designed by utilizing the characteristics of the distributed block chain and a network edge structure, so that a new thought is provided for cross-domain key negotiation based on the block chain.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things equipment, and in particular relates to an authentication key agreement applied by a block chain at the edge of a wireless sensor network. Background technique [0002] Informatization equipment will use the rapid development of artificial intelligence technology to become intelligent, and in this process, edge computing can enable IoT equipment to solve problems such as resource constraints. In the harsh environment at the edge of the network, various IoT devices are vulnerable to multiple security threats. And due to the limited equipment hardware resources in the network edge environment, the security solution based on the alliance chain framework must be both secure and lightweight in terms of processing and storage. However, many existing identity authentication security solutions are not suitable for quality information management applications at the edge of the network, and the ...
