China's independent research and development of key technologies for the Internet of Things have been incorporated into international standards

[China Instrument Network Standard Sharing Circle] On the eve of the 2nd World Internet Conference, China's independent research and development of a key technology for Internet of Things (TRAIS) has been incorporated into international standards. This is China's core technology in the Internet of Things RFID (Radio Frequency Identification System). The first international standard in the field is another breakthrough for Chinese technology companies to participate in the formulation of international standards.

RFID is a key technology for constructing the Internet of Things. It is considered as one of the ten most important technologies in the 21st century, and there is a vast space for industrial development in the future. Therefore, its standard setting has also become the commanding heights for the current advanced economies. In recent years, certain applications have been established in the areas of identification, security access control, electronic tickets, and transportation. RFID technology can be identified completely automatically, without contact, no need to see, so in many places we enjoy the convenience of it, but it does not feel its existence.

The TRAIS core technology from China has been included in the international ISO/IEC standard system, which indicates that China is deeply involved in major global industry core technology activities. It is becoming an important leader in RFID security technology from the spectators and followers of RFID technology standards. By. Huang Zhenhai, an expert from Xidian Jietong Company, head of the TRAIS technology project team, said.

According to reports, RFID-related security technology has not been applied in the early years. In recent years, during the rapid development of the Internet of Things, the security problems exposed by RFID have become more and more severe. The future of the Internet of Things will involve all aspects of human activities, not only involving information security, physical security, and even personal safety. Once attacked, it will have serious consequences.

TRAIS is based on TePA's ternary peer-to-peer security framework developed by Xidian Jietong, and has undergone a decade of research and development. Huang Zhenhai said that TRAIS technology can provide air interface security services such as entity authentication, secure communication, access control, etc. It can resist the security threats such as label forgery, data eavesdropping, and falsification faced by RFID, and it can be used for the wide security use of RFID.

As early as 2012, TRAIS technology was first adopted by the national standard of the Internet of Things core technology RFID. Less than a year later, the technology was adopted by another national RFID standard for commonly used frequency bands. Since then, TRAIS has officially become the national standard for Internet of Things technology RFID.

It is understood that the TRAIS technology project team is led by the WAPI (Wireless Local Area Network Authentication and Security Infrastructure) Industry Alliance, a dozen domestic companies and research institutions, and this wide-ranging approach has also contributed to the achievement of this outcome both domestically and internationally. The effective promotion laid the foundation for the industry.

According to reports, there are currently three major technical standards systems for RFID, namely EPC global led by the United States, UID of Japan, and international ISO/IEC. From a technical point of view, TRAIS technology fully supports these three standard systems.

RFID is the key technology of the Internet of Things. The Internet of Things is another revolution in the world's information industry following the computer, Internet, and mobile communications networks. In November 2005, the International Telecommunication Union ITU issued the "International Telecommunication Union Internet Report 2005: Internet of Things," which defines the Internet of Things as "connecting any item through an information sensing device (such as RFID) with the Internet for information exchange and communication." , can realize intelligent identification, positioning, tracking, monitoring and management."

The Internet of Things will serve as a bridge between the physical world and the virtual world, linking objects to each other, connecting people and people, freeing human resources, and managing intelligence. In order to achieve this effect, the Internet of Things must have three major functions: First, comprehensive awareness; second, reliable delivery; and third, intelligent processing. In the current IoT technology architecture, these three functions are realized by relying on the "perception layer", "network layer", and "application layer", respectively. Among them, the perception layer is the first link of the Internet of Things to sense and acquire information in the physical world.

The sensory layer mainly uses RFID, sensors, etc. to obtain information of objects anywhere and anytime. RFID is a non-contact automatic identification technology. It automatically identifies target objects and obtains relevant data through radio frequency signals. It has the characteristics of small size, easy installation, no need to touch the reader, no manual intervention, and can identify multiple tags with high-speed objects. Compared with traditional barcodes and two-dimensional codes, RFID has obvious advantages and is considered to be the best choice for IoT proximity sensing technology. The International Telecommunications Union (ITU) has listed radio frequency technology (RFID), sensor technology, nanotechnology, and smart embedded technology as key technologies for the Internet of Things.
