Rfid Security Protocols And Encryption Algorithms Research And Realization

Radio Frequency Identification Technology which is always called RFID is very hot in recent years according to its features of small size, high capacity, long life, reusable, as well as support on fast read and write, non-visual recognition, movement recognition, multi-target identification, location and long-term follow-up management. Currently, RFID has been widely used in industrial automation, business automation, transport control and management and so on.However, as the application of RFID expanded, more and more people have paid attention to its security problems including some researchers. The main threats of RFID systems can be divided into two aspects. One is the threat of destroy the system, such as DOS denial of service attack, or disguised as legitimate labels. The other is privacy-related threats.The thesis is raised a creative security protocol and encryption algorithm which is unique on satisfying RFID security and hardware cost, and combine RFID physical properties and cryptography knowledge. Studying on the current framework for RFID security protocols, while analyzing the time cost and hardware conditions of DES and RSA algorithm used in RFID systems, this security algorithm is reasonable and with practical value, which has been practically used in"RFID Access Control and Attendance System"to make communication encryption. And the main problems studied as below:1. Analyze recently security protocol architecture, as well as means of attack.2. Analyze and improve the time cost and hardware conditions of DES and RSA algorithm used in RFID systems.3. Base on the real system, the practical protocol is improved on encryption algorithms and the security framework.4. The theoretical validities are illustrated with simulation results.5. Based on the given frames, the protocol is practically used in"RFID Access Control and Attendance System"to make communication encryption.
