摘　　要：提出了一种TOYOCRYPT-HS1算法高速实现架构,不仅能够满足算法中LFSR特征多项式可变的要求,而且实现了LFSR和非线性布尔函数的并行化设计,显著提高了算法的处理性能。最后通过实验验证和性能比较可以看出,该TOYOCRYPT-HS1算法高速实现架构具有较大的性能优势,最大吞吐率达到1.54 Gb/s。In this paper, a high-speed architecture for TOYOCRYPT-HS1 algorithm is proposed, which can not only satisfy requirements of variable characteristic polynomials of LFSR, but also realize parallel processing of LFSR and nonlinear Boolean function. Finally, implementation and performance comparison have also been accomplished. The results prove that the proposed high-speed architecture for TOYOCRYPT-HS1 algorithm has obvious performance advantage and its maximum throughput can achieve 1.54 Gb/s.
