Because it is non-touching;it can work from long distance;it is fit to work in an unfavorable environment;it can identify moving target, it is widely used in industry, commerce, storage, transportation. This paper introduces the application of the RFID technology and its state of development and discusses the general situation of its application in different fields. Moreover, this paper takes the tourist mini-train as an example, designs a security monitoring system based on RFID and discusses its application in tourist industry.展开更多

During the supply chain management, the tag works in the non-crypto mode in which the on-chip crypto engine is not enabled and the tag chip has a sensitivity of-12.8 dBm for long range communication. At the point of sales （POS）, the tag will be switched to the crypto mode in order to protect the privacy of customers. In the crypto mode, an advanced encryption standard （AES） crypto engine is enabled and the sensitivity of the tag chip is switched to ＋2 dBm for short range communication, which is a method of physical protection. The tag chip is implemented and verified in a standard 0.13μm CMOS process.展开更多

Tag-t（EM is one of its parts by using public-key encryption （PKE） technique to encapsulate a symmetric key. In hybrid encryptions, the long-raessage PKE is not desired due to its slow operation. A general method is presented for constructing Tag-KEM schemes with short-message PKEs. The chosen ciphertext security is proved in the random oracle model. In the method, the treatment of the tag part brings no additional ciphertext redundancy. Among all the methods for constructing Tag-KEM, the method is the first one without any validity checking on the tag part, thus showing that the Tag-KEM/DEM framework is superior to KEM＋DEM one.展开更多

The proposed ap- proach makes full use of scalable data space of ICMP packet to achieve multiple information tags. The difference between this pro- posal and previous proposals lies in two points. First, the number of packets needed by the victim to reconstruct the attack path is greatly reduced because of three key mechanisms： multi-tag, uniform left- over probability, and tag location choice based on the module of accommodated tag numbers within a packet. Second, the true origin of both direct and reflective ICMP-based DoS attacks can be traced.展开更多
