Interactive key security authentication method and system

Abstract

The invention relates to an interactive key security authentication method. The method comprises the steps that a terminal mutual identification certificate is generated; an offline authentication keyproduction management system and an authentication system respectively provide a supplier identity root certificate and a third-party root certificate, respectively generate a supplier identity public and private key pair and a third-party certificate public and private key pair, use the third-party certificate to carry out interactive verification on the public key and then sign, and generate aterminal mutual identification certificate of Internet of Things terminal equipment; the Internet of Things terminal equipment is initialized; the identification SN information is signed by adopting aterminal mutual identification certificate to form an ID signature, and the ID signature and the terminal mutual identification certificate are written into the Internet of Things terminal equipment;and authentication is carried out, and specifically the authentication system verifies the legality of the current terminal mutual identification certificate and the consistency of the ID signature according to the stored supplier certificate, the terminal mutual identification certificate and the third-party certificate, and outputs a verification result. According to the invention, the mutual identification certificate is generated by constructing the key pair interactively generated with the third party, so that the interactive security authentication information is generated.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an interactive key security authentication method and system. Background technique [0002] In recent years, with the rapid development of artificial intelligence, Internet of Things, big data, information communication and other technologies and industrialization, the core technology of intelligent networked vehicles has continuously made breakthroughs, the basic support has been accelerated to improve, and the industrial ecology has gradually matured. A new era It is about to come out, and the way of human travel is facing unprecedented profound changes. With the evolution of product forms and the Industrial Internet of Things, because the background network of the Internet of Things needs the information of connected devices, the production and delivery process of Internet of Things products has gradually increased the product data and security authentication pass...

AI Technical Summary

Problems solved by technology

[0003] Under the new business form of the Internet of Things, many terminal manufacturers have new changes in their equipment requirements, increasing the provision of equipment and other information, security access authentication, etc., relying on manual identification of data information that needs to be provided to terminal manufacturers, which takes a long time. The matching degree is poor, and the data is prone to missing or wrong data, which leads to the inability to activate the terminal manufacturer during production, causing serious impacts such as terminal manufacturers stopping the line
