Internet of vehicles identity management system and management method based on block chain and identification password

Abstract

The invention discloses an Internet of Vehicles identity management system and management method based on a block chain and an identification password, and the system comprises a block chain layer, a management layer and a sensing layer, and the block chain layer interacts with a vehicle, a trusted authorization mechanism, a roadside unit and a key generation center, and completes the identity management, data management and behavior monitoring of the vehicle. According to the invention, a decentralized identity management platform is constructed among the vehicle enterprises by adopting the alliance chain, the vehicle identity authentication process and the identity format of uplink storage are unified, and cross-domain authentication is conveniently realized; a certificate-based authentication mode in a traditional public key password scheme is simplified through a lightweight two-way identity authentication mechanism based on an identification password technology; the MPT is adopted to construct the block chain node, and the storage form of the vehicle information in the MPT is designed according to the form of the key-value pair, so that the vehicle information can be quickly positioned and searched, and the on-chain query speed is increased.

Description

technical field [0001] The present invention relates to a technology in the field of block chain application, in particular to a vehicle network identity management system and management method based on block chain and identification code. Background technique [0002] Existing IoV systems generally use a centralized certificate authority (Certificate Authority, CA) to manage vehicle identities. On the one hand, the centralized system is vulnerable to DDos attacks, which may lead to a single point of failure or cause the identity of the vehicle to be leaked; Forming a unified identity management standard cannot realize the identity authentication of vehicles across management domains. Therefore, the present invention proposes to provide a decentralized management system for each car company based on the block chain. Each car company dynamically joins the alliance chain system as an organization node and manages the vehicles in the domain. The vehicles in each domain are cer...

Problems solved by technology

[0004] The present invention aims at the shortcomings that the existing centralized CA-based Internet of Vehicles identity management scheme cannot form a unified vehicle identity management standard among multiple car companies, it is difficult to realize mutual recognition of identities across management domains, and the authentication process is complicated and inefficient. A car networking identity management system and management method based on block chain and identification password, using the alliance chain to build a decentralized identity management platform among car companies, unifying the vehicle identity authentication process and the identity format stored on the chain, It facilitates the realization of cross-domain authentication; and simplifies the certificate-based authentication method in the traditional public key cryptography scheme through a lightweight two-way identity authentication mechanism based on identity cryptography
