摘　　要：HB+协议是一种基于LPN(Learning Parity with Noise)问题的安全认证协议。由于LPN问题的非线性和复杂性,该协议的安全性能在量子计算机时代远远优于当前的非对称加密协议。基于以上特点,设计了一个以HB+协议为核心的新型安全认证系统,采用密钥型物理非克隆函数引入随机噪声,并采用Toeplitz矩阵进行加密。仿真与实验结果表明,提出的基于HB+协议的认证系统在硬件实现上既简单又安全可靠。The HB+protocol is a security authentication protocol based on the LPN(Learning Parity with Noise)problem.Because of the nonlinearity and complexity of the LPN problem,the security performance of this protocol is far superior to the current asymmetric encryption protocol in the quantum computer era.Based on the above characteristics,a new security authentication system with HB+protocol as the core is designed.The authentication system introduces random noise using a key-type physical non-cloning function and encrypts it using a Toeplitz matrix.Simulation and experimental results show that the proposed HB+protocol-based authentication system is simple,secure and reliable in hardware implementation.
