In this issue, we will talk to Sichuan Changhong Information Security Lab and talk about Sichuan Changhong’s block chain “Internet of things Passport”.

Gold quick shears.

Changhong: focus on the research and development of block chain applications in the Internet of things and the underlying system of the block chain suitable for the Internet of things.

The traditional electrical appliance manufacturing industry conforms to the development trend of the times and is bound to be integrated with Internet enterprises.

Changhong smart family field: block chain helps to solve the problem of trust and realize the real digitalization, networking and informationization of household appliances.

Blockchain technology gives birth to a distributed business model and promotes collaboration and sharing among platforms.

The fragmentation and high degree of collaboration of the Internet of things correspond to the distribution of the block chain, the establishment of data trust and commercial attributes.

Block chain technology solves the problem of dealing with massive data of the Internet of things and realizes the cooperation of devices.

Golden meeting.

Wang Yukun: Hello, everyone. I’m Wang Yukun, the content director of Binance Lab. I’m glad to see you again in the new issue of Golden Binance Lab.

Wang Yukun: today we have invited Dr. Tang Bo, chief scientist of Changhong Information Security Lighthouse Laboratory, and Mr. Yan Lijuan, Communications member of the Block chain Professional Committee of the computer Society of China, to talk with us about the combination of the blockchain and the Internet of things.

Tang Bo: Hello, everyone. I’m Tang Bo from Changhong Information Security Lab.

Yan Lijuan: Hello, everyone. I’m Yan Lijuan from the China Block chain Research Center of Southwest University of Finance and Economics.

Wang Yukun: guest Dr. Tang Bo, Chief Scientist of Changhong Information Security Lighthouse Laboratory. He has served in Ping an Insurance Group, UTSA Cyberspace Security Research Institute and Samsung American Research Institute. In the field of information security has professional technology and rich experience, and through the information system security architecture professional (ISSAP) certification. Eight academic papers have been published and have been cited more than 190 times. The research field mainly focuses on access control, cloud security, IoT security, artificial intelligence security and blockchain applications.

The Exploration of Changhong.

Wang Yukun: without saying much, first of all, I would like to ask Dr. Tang to briefly introduce Sichuan Changhong Information Security Laboratory.

Tang Bo: Hello, everyone. I’m Tang Bo from Changhong Information Security Lab. Our laboratory was established in March 2018 to explore cutting-edge security technologies and overall security solutions for the company.

Tang Bo: at present, we are focused on the security of the Internet of things, and the blockchain is also some ideas slowly made in the security of the Internet of things. Our team mainly considers how to combine with other areas such as blockchain and even trusted computing under the smart family scenario, and the solution is based on these considerations.

Tang Bo: now this plan has gradually evolved from the one at that time. The application of blockchain in the Internet of things and the underlying system of blockchain suitable for the Internet of things are the focus of our research and development, and we look forward to working with people in the industry.

Block chain + opportunity.

Wang Yukun: what is the opportunity and process of Changhong or your personal “+ block chain”? In this process, what process have you experienced in your understanding of blockchain technology and the value that blockchain technology can play in the field of the Internet of things?

Tang Bo: maybe we were familiar with Changhong when we were young. At that time, Changhong was also a very influential brand. With the advent of the Internet and mobile Internet era, as traditional electrical appliance manufacturing enterprises, we are also slowly following the market. In the future, to the era of the Internet of things, the Internet of things means that Internet enterprises and traditional manufacturing enterprises will inevitably merge, whether on the Internet of things devices. Or on the system of the Internet of things.

Tang Bo: we all know that smart families are the main business of Changhong, including a series of household appliances such as televisions, refrigerators, air conditioners and washing machines, which can realize the connection of these household appliances and realize the real digitalization, networking and informationization of household appliances. It is what we want to do in the field of smart families. With the timely emergence of blockchain technology, we find that it can solve the trust problem between equipment and equipment, between equipment and users in this field, and can help us to realize the connection of different kinds and brands of home appliances, so as to facilitate our life.

Tang Bo: we have gone through three stages in the cognitive process of blockchain. In the first stage, we mainly practice the scenario of blockchain technology in the security field of the Internet of things, including device authentication, authorization, automatic discovery of devices and devices, which can operate with each other on the premise of trust. to study the application of blockchain from the perspective of security.

Tang Bo: in the second stage, our trust relationship between devices and devices established by the blockchain itself has been promoted to the trust relationship between the cloud and the cloud, that is, between the platform and the platform. it realizes the trust data sharing and trust collaboration between the platform and the platform. On this basis, some new business models can be generated, for example, platforms and platforms are unwilling to share their data, but users have the need for cross-platform cooperation. The process of sharing these data by blockchain is manageable and traceable, which can be based on this traceability to give birth to a distributed business model to promote collaboration and sharing between platforms.

The development of the third stage is mainly combined with edge computing, which opens not only the platform of the device, but also the edge nodes that aggregate data at the edge, so that the scalability and efficiency of the scheme can be improved. at the same time, it can also increase the protection of user privacy.

The present situation and Challenge of the Internet of things.

Wang Yukun: the Internet of things has become a very frequently mentioned area. In your opinion, what are the development status and challenges of the Internet of things and its applications?

Tang Bo: we have also searched some reports of the Internet of things industry before. As far as we know, the number of devices on the Internet of things in the world will exceed 100 billion by 2025, and according to the world’s population of 8 billion, the number of devices per capita will reach double digits. Such a large amount of equipment will bring extremely fragmented data, and the traditional centralized structure can not carry such a situation, how to solve this contradiction is the focus of our current attention.

Tang Bo: in my opinion, there is a natural combination of the Internet of things and the block chain, mainly because of the fragmentation and high degree of coordination of the Internet of things. It happens to correspond well with the distribution of the block chain, the establishment of data trust and business attributes.

Wang Yukun: 100 billion. Hundreds of billions.

Tang Bo: yes, with such a wide range of connections, the most important problem and the biggest challenge is to break through the trust between devices and form flexible, efficient and penetrating coordination.

Netizen: user information security also needs to be guaranteed, right?

Tang Bo: yes, this is also my view on the application of blockchain in the Internet of things. Distributed computing and storage play an important role in protecting users’ privacy.

Blockchain brings imaginative space.

Wang Yukun: specifically, what problems can the blockchain solve in the current application of the Internet of things? What new imagination space can it bring to the industry?

Tang Bo: based on the trust basis, we can solve some basic security problems in the application of the Internet of things, including device identification and authentication, fine-grained authorization, data audit and traceability. In fact, we understand that blockchain technology is a handy technology, which can be combined with other technologies, such as trusted computing, secure multi-party computing and so on, to bring more vertical solutions.

Wang Yukun: compared with the current solutions available in the field of the Internet of things, is blockchain technology the best solution?

Tang Bo: we have also been paying attention to the field of the Internet of things. Compared with the centralized solution, we think that the addition of blockchain technology can better solve the massive data processing of the Internet of things and the collaboration of devices. Is a better solution.

Wang Yukun: thank you, Mr. Tang Bo! Next, I would like to give the microphone to today’s guest, Mr. Yan of Xicai China Block chain Research Center.

Internet of things passport synergy.

Yan Lijuan: OK.

Dr. Tang, you have mentioned the “distributed trust collaboration solution of the Internet of things” in public. Can you give us a brief introduction to this solution? Please explain the meaning of “synergy” in combination with the application scenario.

Tang Bo: we propose the mechanism of the Internet of things passport, imitating the process mechanism of our international travel, and using the block chain to build the trust relationship between the platform and devices, so as to achieve trust-based collaboration. In addition, this trust structure is also hierarchical synchronous and suitable for a wider range of heterogeneous scenarios, and this network of trust is also the basis for the formation of distributed commerce.

Yan Lijuan: this is the first time I have heard of the passport mechanism of the Internet of things.

Tang Bo: for example, when someone rings the doorbell, the surveillance camera at the door captures the situation at the door and displays it on the TV. The owner can unlock the door through the remote control, which is very convenient.

Wang Yukun: it’s perfect for lazy people like us in the new era!

Yan Lijuan: yes, life is becoming more and more convenient because of the Internet of things.

Yan Lijuan: as we all know, intelligent contract is a very important link in blockchain technology. How is it used in the passport mechanism of the Internet of things?

Tang Bo: specific to the smart home scene, it is also necessary to maintain a certain degree of message consistency. Because there may be a center in this smart home scenario, that is, the so-called edge gateway or edge device, some of our messages may only need to be forwarded locally, and this part of the data may only be stored in the edge device. It will not be synchronized with the cloud, such as our user privacy data; while other devices need to synchronize the relevant data to the cloud to make the data traceable. There may be multicenters in the cloud, all of which are synchronized with edge devices. Our expected goal is to achieve synchronous interworking between local chains and global chains.

Block chain + 5G, AI.

Yan Lijuan: as we all know, the Internet of things has been developed for several years. Is it possible to combine with the block chain at this time to cause a technological singularity?

Tang Bo: 5G itself is the singularity technology that triggered the era of the Internet of things, and AI is also considered to be the industrial direction and future universal form of the Internet of things. In the construction of a digital city, in addition to technology promotion, business promotion is also essential. I think by combining with the blockchain, the Internet of things will usher in a distributed business model, which will become the key to the real popularity of the Internet of things.

Wang Yukun: [by combining with the blockchain, the Internet of things will usher in a distributed business model, which will become the key to the real popularity of the Internet of things. ].

I was so excited that I wish I could roll up my sleeves and work hard right away!

Tang Bo: yes, smart home, smart education, intelligent health, intelligent manufacturing and so on, these application fields will develop rapidly.

Yan Lijuan: block chain + Internet of things = infinite possibility!

Golden message.

Wang Yukun: I would like to ask Dr. Tang to send a message to the new model of “blockchain + industry”!

Tang Bo: building a distributed business with blockchain opens a new era of the Internet of everything!

Tang Bo: thank you, host, thank you!

Yan Lijuan: thank you, Dr. Tang, for your wonderful sharing!

That’s the end of today’s interview ~ thanks to Dr. Tang and teacher Yan Lijuan.

I hope we can go further and further in the application and thinking of blockchain + together.
