Recently, the reporter learned from the official website of IEEE-SA that the international standard of “Blockchain Based Zero Trust Framework Standard for Internet of Things” led by Changhong Holding Group was approved and officially released by the Electrical and Electronics Engineers Standards Association (IEEE-SA). The standard is the first international standard based on blockchain technology in the security application of the Internet of Things, and is jointly developed by authoritative institutions, research institutes and leading enterprises in many countries and regions of the world led by Chinese enterprises, filling the gap in the international standard of IEEE-SA in the blockchain and Internet of Things security.

ALR121-S50 The research and development of the standard lasted nearly 3 years, during which Changhong, as the chairman unit, convened more than 10 formal working group meetings and many technical discussions. The members of the working group include China Mobile, Haier, China Institute of Electronic Technology Standardization, State Grid, Microsoft, Tsinghua University, Zhejiang University, Hong Kong Polytechnic University and other 22 authoritative institutions, research institutes and core enterprises from many countries and regions around the world, gathered more than 50 domestic and foreign industry and technical experts to complete the draft standard. And under the guidance of the IEEEC/BDL Standards Committee, through technical review, online review and proofreading revisions after the final release. It is understood that the international standard aims to provide a replicable and scalable distributed trust core technology framework for Internet of Things applications to reduce the technical threshold and application costs of Internet of Things security systems. The use of iot blockchain technology, integration of zero-trust architecture, support the whole life cycle of iot application trust authorization and behavior certificate, to ensure the security and trust of iot applications, devices, and data.

“At present, the technical architecture proposed by this standard has been applied in the industrial Internet security operation control platform products, and landed in the Changhong Intelligent Manufacturing Industrial Park Industrial Internet scene pilot project.” According to Tang Bo, deputy general manager of Changhong Cloud Computing and Big Data Center, “By building an industrial Internet security operation and control platform, we provide enterprises with a ‘one-stop’ solution for industrial network security and data security, create an industrial Internet security cockpit, and form a multi-level efficient security incident response closed-loop that can cover industrial site level, workshop level, enterprise level and industry level.” Help the digital transformation of enterprises, enabling the upstream and downstream of the industrial chain to “change the number of intelligent”. At the same time, the platform has the ability to conduct global governance of key assets such as industrial equipment, systems and data, support the trusted, controllable and traceable flow of data and shared use, and lay the foundation for exerting the multiplier effect of data elements in the industrial manufacturing field.”

ALR121-S50 Li Ming, chairman of the Blockchain and distributed Ledger Standardization Committee of the Institute of Electrical and Electronics Engineers Standards, said that the implementation of the standard allows blockchain technology to be applied to the framework of the Internet of Things zero-trust security system to reduce the technical threshold and application cost of the Internet of Things security system. Through the promotion of the blockchain-based zero-trust framework of the Internet of Things, building a trusted Internet, and realizing the application of blockchain technology in major scenarios such as the industrial Internet, smart homes, smart health, and smart cities, it will help accelerate the digital transformation and high-quality innovation and development of China’s real economy.
