In the traditional RFID (Radio Frequency IDentification) system, a secure wired channel communication is used between the reader and the server. The newly produced mobile RFID system is different from the traditional RFID system, the communication between the reader and the server is based on a wireless channel, and the authentication protocol is suitable for traditional RFID systems, but it cannot be used in mobile RFID systems. To solve this problem, a mutual authentication protocol MSB (Most Significant Bit) for super lightweight mobile radio frequency identification system is proposed based on bit replacement operation. MSB is a bitwise operation to encrypt information and reduce the computational load of communication entities. Label, readers, and servers authenticate first and then communicate, MSB may be used to resistant to common attacks. The security analysis of the protocol shows that the protocol has high security properties, the performance analysis of the protocol shows that the protocol has the characteristics of low computational complexity, the formal analysis of the protocol based on GNY logic Gong et al. (1990) provides a rigorous reasoning proof process for the protocol.

This paper discourses about a very general problem that occurs in everyday life. In many universities, students are at risk of misplacement or theft of valuables. So, to avoid such mis happening, the development of security system was designed for providing the safety of university student belongings. The proposed security system contains some common information, methodology, schematics and some details related to technical field that is employed into the system, such as RFID (Radio Frequency Identification) and barcode readers along with the design of the established system. For the functioning of the system in a most effectively manner, assumptions with some specific requirements that is needed to be met are encompassed in this paper

Antenna Characteristics

Radio frequency identification (RFID) system has been expected to be expanded in new fields. This paper shows a sensing system for urination by embedding an RFID tag into a paper diaper. The urination could be checked by change of the antenna characteristics. It could be possible to reduce physical and mental strain of both patients and their care personnel. In order to detect the urination, the RFID antenna was designed and the characteristics of the antenna were calculated. In addition, the antenna characteristics were measured with a phantom. As the result, urination considerably changes the antenna characteristics and that the system can be used to detect the urination.

Transmitted Waveform

In car tires coded identification system, radio frequency technology plays a vital role, the key to radio frequency signals transmitted process is waveform modulation. The key of adjusting the waveform is how to match its resistor and capacitor easily. In the paper their resistance and capacitance values are optimized by using the simulation software (Protues) to simulate the transmitted waveform, and based on matching results the optimized physical models are produced. The actual test results agree well with the simulation results. The method of simulation tests can save the resources effectively, and shorten the development time.

Parameter Scheme

Radio Frequency Identification is an Automatic Identification Technology. RFID system typically consists of a reader and a number of tags. When more than one tag send signal to reader at the same time, reader will not identify any one. This is called collision. The information of collision is regarded as uselessness in the conventional algorithms. But in fact, useful information can be extracted from the collision and the reading efficiency can be improved. In this paper, tags use BIBD(16,4,1) blocks instead of RN16, the reader analyses the collision information based on the characteristics of BIBD and makes valid recognition even when more than one tag have been detected in same time slot. The theoretical and simulation results show that the proposed algorithm can improve the reading efficiency by 100% than that of the conventional Q algorithm. Furthermore, the proposed scheme changes little to the existing standard, easy to implement and compatible for EPC Global Code.
