Trustzone-based block chain terminal security guarantee system

Abstract

The invention belongs to the technical field of blockchain Internet of Things, and particularly relates to a trustzone-based blockchain terminal security guarantee system. According to the security guarantee system, a block chain account is deployed on the Internet of Things terminal equipment to realize integration of acquisition, encryption and transmission, and security guarantee is carried out at three levels of kernel, transmission and data; the Internet of Things terminal equipment is divided into a safe area and a non-safe area on the basis of trustzone in a kernel level, and a private key management module is arranged in the safe area to ensure account safety; network access security authentication is carried out at the transmission level, and different levels of encryption are selected according to data tamper-proof and anti-prying characteristics, so that the transmission security is ensured; a block chain function is deployed on an Internet of Things terminal device at a data level, and the block chain function comprises block chain account creation, query, account transfer and the like. According to the invention, the security privacy problem, the main body cooperation problem and the communication compatibility problem in a supply chain system are solved, and credible uplink of data is realized.

Description

technical field [0001] The invention belongs to the technical field of block chain internet of things, and in particular relates to a block chain terminal security guarantee system based on trustzone. Background technique [0002] In recent years, with the popularization and development of the Internet of Everything, the Industrial Internet of Things has achieved application results in many fields, and the production of manufacturing enterprises has become more automated and information has been made public. The public's desire to understand the product supply chain has also become stronger. In the process of industry upgrading and transformation, enterprises need to supervise, store and publicize raw materials, production processes, production equipment, staff, transportation, etc. [0003] With the help of various sensors, positioning systems, identification devices, etc. of the Internet of Things terminal equipment, the world has realized the interconnection of things an...

AI Technical Summary

Problems solved by technology

[0006] (1) Security and privacy issues: servers are vulnerable to DDOS attacks, personal data is easy to leak, IoT identities are easy to be forged, information is easy to be tampered with, etc.

[0007] (2) The problem of subject cooperation: mutual distrust between multiple subjects, to establish the ability to identify other subjects, it is necessary to establish a wide range of identification and information disclosure mechanisms

[0008] (3) Communication compatibility issues: The vigorous development of the Internet of Things has promoted many branches to do their own thing, communication is incompatible with each other, languages ​​are not unified, platforms are diversified, and intelligent processing of data is required

[0009] Therefore, the information obtained from traceability supply chain data cannot guarantee the authenticity
