Study On Integration Of Security Mechanisms Of The Anti-collision Protocol For RFID

RFID (Radio Frequency Identification) technology is a branch of automatic; identification technology, and as a new automatic identification technology for its rapid, real-time, accurate collection of features in many fields widely used. In the course of development of automatic identification technology has appeared in a variety of technologies, which are disproportionately, but the most competitive RFID technology, developed rapidly, RFID systems market has become the information industry one of the fastest growing markets.At the same time, RFID technology is a tool for technology, must be associated with a particular combination of applications, from minutes to play to their high efficiency, automation and so on. Systems based on RFID technology development and implementation of deployment shooting multi-disciplinary, multi-field knowledge and methods, involving information, manufacturing, materials, equipment and technology, and many other cutting-edge and high technology, covering technology, including wireless communication, computer network, control theory, information systems and management science. Today, RFID technology has become widespread in many areas a focus of attention.So far, many experts on the anti-collision algorithms and secure authentication protocol for some studies, but studies are carried out separately, and very little to break the routine of a comprehensive study of the two. This paper discusses the structure of RFID system components, the system described FRID impact of existing algorithms and the more popular security authentication algorithm. And then through the CDMA multiple access communication technology capacity to solve the problem of collisions RFID systems, and full use of its security, confidentiality and the advantages of anti-interference ability, combined with authentication key and the cyclic redundancy check code CRC, irreversible hash function, species proposed for low-end RFID systems integration of security mechanisms anti-collision algorithm. In addition, the paper also gives the software implementation of the algorithm. Integration of security mechanisms are given the anti-collision algorithm, and algorithm function has a simple description, and analysis of algorithms related to performance. RFID applications in this study can provide theoretical basis for support and promotion, and also to open up a new RFID application model, the application of RFID to promote to a higher level.This innovation is mainly reflected in:[1] anti-collision algorithm for RFID is now a number of deficiencies, a code division multiple access technology through multiple access communication capabilities to solve the collision of RFID systems approach.[2] from a different angle. RFID technology for global research. RFID is now mainly a single aspect of research, one of the safety study, the second is to study the collision, and this issue is up from a global study will allow the two as a whole.
