为解决射频识别(RFID)技术在用户隐私方面存在的安全隐患，提出一种基于NTRU密码体制的新型RFID双向安全认证协议，从大维数格中寻找最短向量。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NTRU公钥加密方案，通过对比原Hash值与解密后的Hash值是否相等，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和位置隐私，而且还能防范重放攻击，满足RFID系统的安全性要求。

To solve the user privacy security problems of Radio Frequency Identification(RFID), a new mutual authentication security protocol of RFID based on NTRU cryptography is proposed, and the security is based on the difficulty of finding a very short vector in a lattice of very high dimension. This protocol is superior in security, computational complexity and efficiency compared with those based on RSA and symmetric cryptography. The protocol proposed uses NTRU public key cryptography with Hash function embedded. By comparing the original Hash value with 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 is an effective way to protect RFID systems.
