量子算法对当前的密码系统构成了巨大的威胁。在这篇文章中，我们提出了一个硬件实现的晶体KYBER，这是一个后量子密码系统的基础上模LWE问题。该设计利用提出的模约简算法、改进的模加法器和可重构的数据路径，实现了不同多项式相关运算的计算资源共享，实现了较高的并行度。我们的设计是在Xilinx阿蒂克斯-7 FPGA上实现的。与领先的硬件实现相比，我们的设计更紧凑，执行时间更短，它显着消耗更少的寄存器。
Quantum algorithms pose a huge threat to the current cryptosystems. In this article, we present a hardware implementation of CRYSTALS-KYBER which is one of the post-quantum cryptosystems based on the Module-LWE problem. Using the proposed modular reduction algorithm, modified modular adder and the reconfigurable data path, the design shares the computing resource for different polynomial related operations, and achieves higher degree of parallelism. Our design is implemented on a Xilinx Artix-7 FPGA. Compared with the leading hardware implementations, our design is more compact, the execution time is shorter, and it significantly consumes fewer registers.
