Quantum computers have the potential to solve difficult mathematical problems efficiently, therefore meaning an important threat to Public-Key Cryptography (PKC) if large-scale quantum computers are ever built. The goal of Post-Quantum Cryptography (PQC) is to develop cryptosystems that are secure against both classical and quantum computers. DME is a new proposal of quantum-resistant PKC algorithm that was presented for NIST PQC Standardization competition in order to set the next-generation of cryptography standards. DME is a multivariate public key, signature and Key Encapsulation Mechanism (KEM) system based on a new construction of the central maps, that allows the polynomials of the public key to be of an arbitrary degree. In this paper, a high-throughput pipelined architecture of DME is presented and hardware implementations over Xilinx FPGAs have been performed. Experimental results show that the architecture here presented exhibits the lowest execution time and highest throughput when it is compared with other PQC multivariate implementations given in the literature.

量子计算机具有有效解决难题的潜力，因此，如果建造了大型量子计算机，这将对公钥密码术（PKC）构成重大威胁。后量子密码术（PQC）的目标是开发对经典计算机和量子计算机都安全的密码系统。DME是针对NIST PQC标准化竞赛提出的抗量子PKC算法的新建议，旨在设定下一代密码标准。DME是基于中央映射的新构造的多元公共密钥，签名和密钥封装机制（KEM）系统，它允许公共密钥的多项式具有任意程度。在本文中，提出了DME的高吞吐量流水线架构，并已通过Xilinx FPGA进行了硬件实现。实验结果表明，与文献中给出的其他PQC多元实现方案相比，此处介绍的体系结构具有最低的执行时间和最高的吞吐量。
