1. Most RFID chips are easily cracked. Problem analysis: Because the cheapest and most popular RFID chip has no battery, it is powered by a card reader when scanning, and it lacks its own power supply system. This chip is also vulnerable to the attack of "stealing electricity by energy consumption". Some professionals have been able to invade RFID tags and develop corresponding password killers (a kind of code that can make tags self-destruct).
Countermeasures: At present, China basically has the ability to design and develop RFID antennas, but it does not have the ability to design reliable RFID tag antennas for metal materials and liquid environments. At present, UHF tags cannot be packaged, and the packaging equipment still depends on imports; Without the design and manufacturing capabilities of readers above UHF band, the security risks of RFID chips cannot be fundamentally solved. Therefore, we should learn from advanced RFID technology countries, strengthen the research and development of RFID technology, and finally move towards completely independent development.
2.RFID security issues. Problem analysis: RFID industry will soon become the next battlefield for computer hackers. Various attacks on RFID system, such as rewriting labels and tampering with item information; Using special equipment to forge label replies to deceive readers into making false images of articles; According to the asymmetry of RFID forward and backward channels, the tag information is eavesdropped at a long distance; Denial of service attack is implemented by interfering with RFID working frequency; Destroy labels by emitting specific electromagnetic waves. The money temptation of RFID hackers is growing, because more and more RFID tags are used for credit card payment and other financial transactions, which will become a very serious problem. Suppose a hacker enters a store, buys a product with an "electronic tag" (RFID) and takes it home; Then he tore off the label and attached another label containing malicious code; He went back to the store and asked the cashier to scan the product again. In this way, malicious code enters the store's computer system, changes the price and sales data of products, and creates a login port for external visitors to enter the store's database.
With the function of RFID chip becoming more and more complex, the risk of being attacked is getting higher and higher. The new generation of computers are usually more complex and have more functions, which leads to increasingly prominent security problems. According to a report published last year, someone has cracked more than 65.438 billion car keys with RFID system. In order to crack the password, the hacker connected the 654.38+0.6 chip and programmed it to find out the password contained in the tag. These are the key security issues that need to be considered when implementing RFID in China.
Corresponding countermeasures: while vigorously promoting the application of RFID in China, we should take corresponding measures, increase investment, and carry out targeted research on RFID security packaging technology to improve the security performance of RFID tags.
3. Malicious people invade private privacy through RFID. Problem analysis: RFID will become a tool for malicious people to invade private privacy. The security problems of RFID mainly focus on the privacy protection of individual users, the protection of business secrets of enterprise users, the prevention of attacks on RFID systems and the use of RFID technology for security prevention. The challenge is: (1) Users' ownership information of labels will not be accessed without authorization, so as to protect users' privacy in consumption habits and personal whereabouts. (2) RFID system can quickly scan all the goods in the supermarket and track the changes, so it can be used to steal the business secrets of users.
Countermeasures: (1) The protection of RFID infringement in China is not perfect enough and needs to be further improved and supplemented. (2) Developing self-destruction or degaussing labels to solve this problem; Cooperate with nanotechnology to develop ultra-small labels suitable for special items; (3) In view of the privacy of RFID, China should encourage the development of "clippedtag" technology, so that consumers can tear off or scrape off the RFID antenna, and the tag cannot be read at will. Research and design a command to disable RFID tags, and it is an irreversible operation. When consumers return goods, RFID tags cannot be read, which can prevent privacy from being violated. (4) Use hash lock to solve this problem: reader authentication. Before responding to the reader and allowing the reader to obtain the tag ID information, the reader and the tag determine the authentication system. Because the reader ID of the reader is pre-stored in the RAM of the tag, the tag identifies the reader with authority through the reader ID. Tags don't respond to readers without permission, so they can't be tracked by enemies (because readers have permission). In addition, this authorization process is based on the random number generated by the tag, so it can also prevent the enemy from spoofing. Therefore, China can not only introduce foreign advanced science and technology, but also improve and innovate on the basis of existing technology according to specific problems and solve these problems.
4.RFID technology talent gap. Problem analysis: At present, the number of people who master RFID technology is still below the market demand. According to the survey, some companies need to spend more time and money on training and educating their employees.
Corresponding countermeasures: setting up RFID courses in colleges and universities to lay a foundation for technical talents in building RFID technology with China characteristics in the future; In addition, the state has increased the research and development of RFID technology, and encouraged more high-quality talents from enterprises to participate in the study, research and application of RFID, which has laid a solid talent foundation for the application of RFID technology in all walks of life in China.
5.RFID cost problem. Problem analysis: RFID will not only encounter resistance from cost before landing in China, but also face the problem of which industries will take the lead in making breakthroughs. "By 2007, half of the existing RFID projects will fail!" This is a pessimistic prediction made by authoritative companies recently. According to industry experts, the relatively high production cost of RFID is the main reason why most domestic supermarket chains are discouraged.
Countermeasures: In order to reduce the cost of RFID, RFID manufacturers can unite with chip manufacturers at home and abroad to continuously improve the technical performance of RFID and reduce its cost. In addition, we should study and explore a more efficient operation and management mode to reduce costs.
The opening of 6.6. RFID implementation standard. Problem analysis: At present, the international UHF RFID technology mainly uses about 430MHz and 860 ~ 960 MHz, while in China, the 430MHz band is a special band, and the conditions for opening RFID services in this band are not mature at this stage. The main business of 860 ~ 960 MHz frequency band is fixed and mobile, and the secondary business is radio positioning. There is no idle frequency in this frequency band in China, so it is directly planned for RFID.
Corresponding countermeasures: China should consider the supply of RFID service and the existing radio service frequency when considering RFID frequency planning according to its own national conditions. And strive to build China RFID technical standards (such as symbols, radio frequency identification technology, IC card standards) and data content standards (such as coding formats, grammar standards, etc.). ), consistency standards (such as printing quality, test specifications and other standards) and application standards (such as transport labels, product packaging standards and so on. ) as soon as possible.
7.7 development. The development of RFID industry lags behind. Problem analysis: chip design and manufacturing, antenna design and manufacturing, label packaging and packaging equipment manufacturing, reading and writing equipment development, data management software design? 6? 8u8943。 Each production link constitutes a complete RFID industrial chain. At present, there are chips based on 13.56MHz band, and the UHF chip, which is the most widely used in the world, is still under development. This research and development is based on ISO standard. The lagging development of the industry, especially the lack of core technologies, has become an insurmountable wall for the formulation of RFID standards in China, and the lack of RFID China standards has in turn restricted the development of the industry. There is no RFID China standard, which will not only affect the application of RFID by users, but also affect the research and development of enterprises.
Corresponding countermeasures: China should formulate domestic standards for RFID as soon as possible according to the national conditions and the newly promulgated RFID application standards. Only with standards can we promote the in-depth application of RFID technology and promote the development of RFID industry.
Four. conclusion
Generally speaking, the future development of RFID system is very promising in many industries. Although there are still some technical and application problems, I believe it is just around the corner to overcome all kinds of hidden dangers of RFID. Under the strong market orientation, RFID technology will surely lead to major changes in the world, become a new economic growth point in the future, and finally become the biggest information technology support for the development direction of enterprises in China. It is believed that in the near future, RFID technology will go deep into the modernization of China like barcode technology, and gradually extend to all aspects of various industries, which will play a key role in improving operational efficiency and economic benefits, increasing the income of various industries, and promoting China's national economy to achieve a new leap.
