ZUC算法的高性能硬件架构
High-Performance Hardware Architecture of ZUC Algorithm
摘要
Abstract
ZUC(ZU Chongzhi),a stream cipher algorithm developed in China,has been upgraded to ZUC-256 to meet the challenges of 5G communication and the post-quantum cryptography era.To fulfill the high-performance requirements posed by complex scenarios,such as ultra-reliable and low latency communication in 5G,this study focuses on designing a high-throughput ZUC hardware architecture based on the ASIC platform.Firstly,this study proposes a method of modulo(231-1)additions based on multiple addends.Leveraging this method and multi-stage pipeline technology,this study successfully reduces the critical path of the self-feedback loop of the linear feedback shift register to a 32-bit adder,significantly reducing clock cycles and enhancing the system's operating frequency.Secondly,this study dissects the modulo 232 additions structure of the finite state machine with the aim of optimizing its latency,making the critical path equivalent to a cascade of one 16-bit adder and one multiplexer.Experimental results indicate that,the proposed architecture achieves a maximum operating frequency of 1470 MHz and a throughput of 47.04 Gbps,marking a 22.5％improvement in throughput compared to existing researches,under the TSMC 90 nm process library.关键词
