【摘要】 MIFARE Classic卡作为使用最多的RFID卡,被广泛应用于公交、门禁、城市一卡通等系统。但最近越来越多的研究者发现它存在致命的安全漏洞,很容易受到攻击。文中首先介绍了MIFARE Classic卡的基本结构特性;然后结合实用性和安全性,针对MIFARE Classic卡的一般应用系统和特定应用环境给出了一些可以提高它安全性的建议,这些建议不仅对现有MIFARE Classic系统的改造有指导意义,而且对未来新系统的建立也有借鉴作用;最后简要地给出了一种替换MIFARE Classic卡的过渡方案。更多还原

【Abstract】 MIFARE Classic card is the most popularly used RFID card in public transport system,access control system,city card system,etc.Recently,more and more researchers have found its fatal flaws,which would result in some attacks on MIFARE Classic itself.In this paper,the features of MIFARE Classic card is first described.Then by considering application and security of the system,some security suggestions are proposed for the common application systems and some special systems respectively.Those suggestions are helpful to improving the current system while to building a new system in the future.Finally,an interim scheme on replacing MIFARE Classic card is presented.更多还原
