中文摘要：

通过分析Cichoń,Klonowski和Kutylowski提出的射频识别安全认证协议,发现该协议在安全性上存在一定的漏洞,进而提出了两个攻击算法,包括主动攻击和被动攻击.算法以协议中的置换为目标,试图从特殊的置换入手,逐步找出协议中所使用的特定置换,进而成功的对协议进行攻击.

英文摘要：

RFID security authentication protocol proposed by Cichoń,Klonowski and Kutylowski was analyzed and found some security breaches in it.Against the protocol,two attacks were put forward,both active and passive.They aimed at the permutation of the protocol,tried some special ones to make sure the real permutation of it,and then,succeeded in attacking.
