摘　　要：为解决RFID技术在用户隐私方面存在的安全隐患,提出了一种基于Niederreiter密码体制的新型RFID双向安全认证协议。协议建立在大矩阵分解困难性的基础上,与使用对称密码和RSA公钥密码的协议相比安全性能更高、计算复杂度更小、实现效率更高。该协议利用基于嵌入Hash函数的Niederreiter公钥加密方案,通过对比原Hash值与解密后的Hash值是否相等,来实现RFID标签与阅读器之间的安全数据交换。研究结果表明,该协议不仅能有效地保护内容隐私、位置隐私,而且还能防范重放攻击,能够很好地满足RFID系统的安全性要求。To solve the user privacy security problems of RFID, a new mutual authentication security protocol of RFID based on Niederreiter cryptography is proposed, and the security is based on the difficulty of large matrix decomposition problem. This protocol is superior in security, computational complexity and efficiency compared to those based on RSA and symmetric cryptog- raphy. The protocol proposed uses Niederreiter public key cryptography with Hash function embedded. By comparing the origi- nal Hash value to the Hash value decrypted, the data exchanged between RFID tag and reader can be protected. Research and analysis show that this protocol can effectively defeat content and location privacy attack, as well as relay attack, and can effec- tive protect RFID systems.
