1 Introduction to RFID system
1.1 RFID working principle
The working principle of the RFID system is that after the corresponding tag enters the magnetic field, it receives the special radio frequency signal emitted from the reader, and then stores the obtained energy through the induced current, and harvests the corresponding product information. Or it is actively sending a signal of a certain frequency, sending it to the reader for reading and decoding, and then uniformly transmitting it to the central information system, and then performing related data processing.
1.2 RFID system composition
The radio frequency identification system has two components: a reader and an electronic tag. The content of an electronic tag can also be called a radio frequency card, a transponder, etc., collectively called an electronic tag. In addition, it also includes content such as antenna and host. In the actual application process of the RFID system, according to the difference in the environment and the final purpose, different system components are formed. However, from the perspective of the working principle of the RFID system, the RFID system generally consists of the following four parts, namely Signal transmitter, signal receiver, transmitting antenna and receiving antenna. According to the different functions of the system, the system is divided into four categories, namely portable data acquisition system, positioning system, network system and EAS system.
2 Potential safety hazards in the RFID system
At present, the RFID system mainly obtains attacks from the outside world by intercepting the information of the tag and cracking the information. After obtaining the information in the tag, the outside world can forge the information, thereby illegally attacking the RFID system. Authorized use, according to the results of the study, if there is no contact with RFID, there will be the possibility of stealing the information in the system, and the encryption effect in the system is not very ideal. The label information encryption of the RFID system is its main protection method, but the protection method provided by the RFID system cannot fully protect the security of the information. If the system cannot be fully protected due to the internal chip design, The data and information stored in Xinchang can be obtained through other methods, and relying solely on the technical characteristics of the system itself cannot meet the standards for protecting internal information.
With the continuous development and improvement of technology, the functions of RFID chips are gradually developing towards a diversified trend. Therefore, the risks that are assumed are getting higher and higher. For the new generation of computers, although their function types are more comprehensive , But usually the structure is more complex, and the number of security problems caused is also increasing. There are high-risk loopholes in many systems. Therefore, the development of RFID system needs to address the security issues in the system. At present, the hidden security problems in the RFID system mainly include the following points.
2.1 Labeling issues
The size of the label is small, but there are high safety hazards and safety risks. The tags in the RFID system can easily be manipulated by unqualified employees or hackers. The main reason for the security problems of RFID tags is that the designer did not carry out support points during the process of designing the tags. Encryption, and there is no corresponding PKI key exchange function installed on the label.
2.2 Network problems
In the process of transporting goods or retailing, it will provide some criminals with an opportunity. The criminals will take this opportunity to tamper with the data on the RFID tag, so as to achieve the purpose of stealing the internal information and data of the tag. In addition, for the company’s distribution center, or some store warehouses, network security has greater security risks, which will provide some criminals with opportunities to steal data through wireless networks.
2.3 Data issues
One of the most obvious advantages of the RFID system is to enhance the transparency of the supply chain. However, as the state of transparency improves significantly, the risks and threats brought by the protection of data security are increasing. If an enterprise wants to provide a reliable guarantee for all data, it must not only guarantee the security of its own quality information, but also the security of the information and data of its trading partners and cooperating partners. At present, no companies have taken corresponding measures to protect the data of their partners, and the protection measures and protection methods are often not scientific and reasonable, and to a certain extent, they are stolen by criminals. Information and data provide opportunities.
3 Suggestions for the safe development of RFID technology
3.1 Attach great importance to the hidden dangers of RFID
The functions and functions of RFID and the Internet are relatively similar. In the initial stage of application design, it is in a completely open state. Therefore, the future development of RFID systems will be the same as the Internet, facing some security issues. However, due to the low cost of RFID itself, some security tools with good performance cannot be put into the process of system operation, which adds a certain degree of difficulty to the solution of RFID security problems. In the development process of RFID technology, the domestic urgent need to attach great importance to system security issues, we should fully realize the importance of system security issues, give full play to the advantages of domestic network security, and contribute to the long-term logistics development and information in the future. Management takes far-reaching considerations, and follows the pace of international development, and actively develops security technology research related to RFID technology, so as to provide a reliable security guarantee for the future development of RFID.
3.2 Strengthen RFID technology research
In the research of RFID technology, the limited resources and the improvement of security intensity are the biggest challenges faced by RFID research work. From the perspective of RFID technology security research work, how to reduce costs while ensuring security is a first-choice content for research work. In order to solve the security problems in technology, it is necessary to conduct sufficient research on label encryption technology. Encryption technology can effectively prevent intruders from stealing information and data in RFID tags. However, the cost of traditional encryption methods is too high. At present, only a few expensive items will adopt this high-cost encryption method to protect data. Therefore, in the current field of RFID technology research, the research on some low-cost security technologies needs to be strengthened. From the perspective of own security and interests, fully develop and study its own RFID tag encryption technology, so as to achieve a limited cost. Play an infinite role for this scientific purpose.
3.3 Establish an RFID security system
From the current point of view, all countries in the world have established safety standards for RFID from the perspective of their own interests and safety, and a confrontational situation has also been formed in Japan and the United States. my country has also started research on its own RFID technology, but it has not provided a standard for data protection on the Internet. With the continuous advancement of science and technology in my country, data sharing has been realized between enterprises and enterprises. Security protection measures are very important for the development of enterprises. In order to ensure the safety of RFID technology tags, we are formulating and applying RFID protection standards At the same time, a safety standard system suitable for the development of domestic RFID technology should also be constructed to continuously provide favorable conditions for the growth and development of the logistics system.
4 summary
In summary, for RFID technology, the system itself not only has powerful functions and a wide range of applications, but also, with the improvement and development of RFID technology, RFID technology is bound to achieve considerable and broad development in the future. The development prospects of the company constitute a global Internet organization, which plays a vital role and influence in the development of global logistics. Therefore, with regard to the hidden dangers of RFID technology, it is necessary to continuously develop security methods to protect the information in RFID tags from the perspective of its own security and interests, and construct RFID security technology protection suitable for the characteristics of domestic development. System, strengthen the research work of RFID security technology, so as to lay a solid foundation for the future development and growth of domestic logistics.
