摘　　要：f8加解密算法和f9完整性算法广泛地应用于移动通信网络安全中,但f8、f9算法性能目前仍满足不了移动网络安全高吞吐率的需求.由此提出了一种新的22合1结构,该结构以Snow3G算法为核心,并且支持f8算法和f9算法.在Quartus II 13.0下采用Altera的Stratix V系列5SGSMD8N2F45I2型号FPGA综合,f8_f9单核模块的时钟频率能够达到292.40 MHz,f8算法吞吐率达到了9.36Gb/s,f9算法吞吐率达到了4.68b/s.Snow3G作为核心模块,吞吐率能够超过10Gb/s,占用482ALMs,性能上超过了同类设计,满足了高性能的要求.Algorithms for confidentiality f8 and integrity f9 have been widely applied to the security of mobile communication network.However,the performance of f8 and f9 nowadays still doesn′t satisfy the requirement of high throughput application in the security of mobile communication network.In this paper,we proposed a novel 22-in-1 architecture,which is based on Snow3G algorithm,and it supports both f8 algorithm and f9 algorithm.The f8_ f9 single module has been synthesized under Quartus II 13.0 and implemented by Altera Stratix V series 5SGSMD8N2F45I2 type FPGA.The throughput of f8 algorithm reaches 9.36 Gb/s at 292.40 MHz and 4.68 Gb/s for f9 algorithm.The kernel Snow3G module reaches a throughput more than 10 Gb/s and takes up 482ALMs, which is better than other design in performance and meets the demand of high performance.
