摘　　要：针对射频识别(RFID)搜索协议的特殊性,对RFID搜索协议的安全需求进行了扩展,并根据扩展后的安全需求,对原先的SSP协议进行一些必要的安全性增强和改进,提出了一种可防碰撞的RFID安全搜索协议,称之为SSP+协议。对SSP+协议的安全性分析表明,改进后的RFID搜索协议不仅能满足隐私保护、匿名、并发安全、防追踪等一般性的安全需求,还能消除因碰撞问题造成的安全隐患,满足了防碰撞这一搜索协议独特的安全需求。According to the particularity of search protocol for RFID,its security requirements were extended in this paper.Then,on the basis of the extended security requirements,some security enhancements and improvements on the original SSP protocol were achieved,and a secure anti-collision search protocol for RFID called SSP＋ protocol was proposed.Subsequently,based on security analysis of SSP＋ protocol,it was proved that this improved protocol can not only provide general security requirements,such as privacy protection,anonymity,untraceability,but also eliminate security risk caused by collision,thereby meeting anti-collision that is the unique security requirement on search protocol.
