改进的抗去同步化攻击RFID安全协议

摘要

纵观目前已有的轻量级RFID安全协议,制作成本普遍较高且部分协议无法完全抵御主流的RFID攻击,为此提出一种改进的抗去同步化安全性RFID网络协议.结合Rabin加密算法以及随机数自更新机制,基于加密的ID、安全密钥KEY、随机数进行标签-阅读器-后端服务器系统之间的双向认证(默认数据库合法),实现对各种攻击的抵御.证明和比较结果表明,该协议具有较高安全性,具备计算效率更高、制作成本更低、内存需求更低等优势.%Most of the existing lightweight RFID security protocols are highly costful and some of the protocols cannot resist some mainstream RFID attacks.An improved resistance de-synchronization attack RFID security protocol was proposed,which implemented resistance to various attacks.Rabin encryption algorithm and random number automatically update mechanism were combined,based on the ID,safe and secret encryption KEY and some random numbers,mutual authentication between tag and reader-backend database was realized.Demonstrating and comparing results show,the protocol is highly secure,and it has higher efficiency,lower cost and requires smaller memory.
