| dc.description.abstract | Radio Frequency Identification (RFID) is a technology to automate identification by radio wave signals. Due to the convenience brought by its non-contact and non-directional characteristic, the applications related to RFID are very wide so that RFID have been considered as one of indispensable important society infrastructure in the future life. However, because of RFID tags inherent limitations of hardware resources and the nature of radio waves to communicate, there are many security issues in RFID systems, and RFID authentication protocol is one kind of methods to ensure the security of RFID systems.
Many RFID authentication protocols are proposed currently, but most of the research hypothesis of current RFID authentication protocols don’t take into consideration the insecure communication environment in mobile RFID systems, which can’t be applied to mobile RFID systems. Besides, many RFID authentication protocols bring overmuch computation load to RFID tags, which doesn’t conform to the lightweight operations in EPC international standard, or make back-end server spend too much cost to search RFID tag data, which affect the RFID system performance, so they can’t solve the security issues in RFID systems effectively.
Against these problems, this study proposes a new RFID authentication protocol named“DEAP: A Dynamic and Efficient Authentication Protocol for Mobile RFID Systems” to solve the potential security issues in mobile RFID system environment. Moreover, all operations in DEAP conform to the lightweight operations that EPC formulates, and the back-end server only use few computation to query RFID tag and reader data, which achieves to ease the computation load of RFID tags, RFID readers and back-end server as well as improves system efficiency effectively..
Finally, through analysis and comparison, we prove the new RFID authentication protocol that this study proposes can indeed ensure the security in mobile RFID systems to resist all kinds of RFID attacks, and also quantify as well as compare the computational complexity that DEAP needs. | en_US |
