【摘要】 RFID技术广泛应用的同时,其安全问题面临着严峻的考验。在确保安全性能的前提下,节省系统成本、提高效率成为未来研究重点。在分析各种协议缺陷之后,借鉴滚动码技术的同步数原理,提出了一种基于同步数的轻量级高效RFID身份认证协议。协议运用同步数以及双向认证机制保障系统安全性。对各种威胁进行分析,确保了协议的安全性。通过比较其他协议的效率与成本,可以看出该协议具有轻量级与高效性。最后运用BAN逻辑对协议进行了形式化分析,从理论上证明了本协议的可行性。更多还原

【Abstract】 While RFID technology is widely used,its security is facing serious challenges.Under the premise of ensuring safety performance,how to save system cost and improve efficiency has become a research focus.We propose a lightweight and efficient RFID authentication protocol base on synchronization code after analyzing the defects of various protocols and referring to the synchronization digital principle of code hopping encoder.This protocol guarantees the security of the system by using synchronous number and bidirectional authentication mechanism,and analyzes the threats to ensure the safety of the protocol.Comparing with other protocols,the proposed protocol is of low cost and efficient.Finally,the BAN logic protocol is adopted for a formal analysis,which theoretically proves the feasibility of the proposed protocol.更多还原
