Research On Identity Authentication System Of Internet Of Things Based On Trust Anchor

In recent years,the Internet of things equipment has been widely used in transportation,warehousing and logistics,smart home and many other fields,in which the security of the Internet of things and related equipment also affects the future development of each industry.However,there are still many deficiencies in the security protection of the Internet of Things,user privacy data have a higher risk of leakage in the process of communication and transport,in addition,the traditional certificate-based identity authentication scheme also has security issues such as cross-authentication and single point of failure between different visa subjects,which makes the IOT equipment urgently need to realize two-way identity authentication and data encryption transmission.Based on the above situation,the paper carried out the following research:(1)The research on trust anchor model.This paper designed a set of efficient and secure unified trusted authentication and management mechanism for the whole network,proposed a distributed trust anchor architecture based on Zookeeper,which can store the public key information of the Internet of things platform and all the embedded devices connected to the platform,so that the remote communication entity can obtain the public key information of the opposite party and ensure the authenticity of its public key information,and realized all parties in the Internet environment can be interconnected equally,safely and credibly.(2)Designed a set of identity authentication protocol suitable for the platform and equipment of the Internet of things,which can realize the two-way identity authentication key negotiation between the lightweight esp8266 embedded terminal equipment and the platform of the Internet of things,so as to jointly build a secure,low-cost and intelligent Internet of things environment.(3)The design and implementation of the Internet of things identity authentication system based on the trust anchor,using Java as the main development language to realize the Internet of things platform,which can realize the remote collection of the relevant data information collected by the Internet of things equipment,monitoring and managing all the Internet of things equipment connected to the Internet of things platform.Based on the new trust anchor framework,this paper constructed an identity authentication system of the Internet of things,which can realize the two-way identity authentication and encrypted data transmission between the Internet of things platform and the embedded devices of the Internet of things.In addition,the experimental results prove that the trust anchor model not only supports the stable operation of public key information update and query operation,but also has good usability with the increase of the number of trust root nodes.
