摘　　要：针对射频识别系统中标签与读卡器会话存在易被攻击者窃听等安全问题,提出一种基于R_LWE(Learning with Errors over Ring)密码体制加解密的RFID双向认证协议。协议采用R_LWE密码体制实现加密的同时引入交叉合成运算,既可确保安全性,亦可降低计算开销。结合不同攻击类型、逻辑形式化分析、性能角度综合分析,该协议具备安全等级高、计算量小等优势。Aimed at the security problems that the session between tag and card reader in RFID system is easy to be eavesdropped by attackers,a method based on R_LWE encryption and decryption of RFID two-way authentication protocol is proposed.The protocol adopted R_LWE cryptosystem to implement encryption and introduce cross synthesis operation,which could ensure security and reduce computing overhead.Combined with different attack types,logical formal analysis and comprehensive analysis from the perspective of performance,it shows that the protocol in this paper has the advantages of high security level and small amount of calculation.
