摘要
目前射频识别(RFID)系统的安全受到越来越多的重视。该文在总结目前存在的主要攻击方式的基础上对现有RFID系统安全保护协议进行了分析,针对现有协议的弊端在原有的Hash-Lock协议基础之上引入DES算法设计出一种新的阅读器和标签相互认证协议,并对新协议的执行过程进行了详细论述,最后对新协议的性能进行了分析。分析结果表明,新协议能够弥补现有协议的不足,更好的适应射频识别用户对自身安全和隐私进行保护的需要。
In modern time,the security of radio frequency identification(RFID) get more and more attention. Based on the summarization of the existing primary attack of the system, this paper analysis the security protocols available today. Aimed at the disadvantages of existing protocols, a new authentication protocol between reader and tag is developed by introducing the DES algorithm to the Hash-Lock protocol. Then, discusses the implementation process in detail. Finally analyses the performance of the new protocol. The analysis result shows that the new protocol can make up for inadequacy of existing agreements and can meet the needs of RFID users to protect their own information security and privacy.
