DESIGN AND RESEARCH OF HIGH-EFFICIENCY HIERARCHICAL BIT-EXTRACTION NETWORK FOR STREAM CIPHER
摘要
Abstract
Aiming at the problems in stream cipher algorithm that the high areas of the reconfigurable hardware implementation of bit-extraction,we propose a high-efficiency hierarchical bit-extraction network based on the Inverse Butterfly network named HHBN (High-efficiency hierarchical bit-extraction network),through the studying of the nonlineal boolean function in stream cipher algorithm.Compared with other networks,the proposed network can extract multiple sets data with common variables.The actual performance and flexibility of HHBN are better than most other networks,and area is far less than the Crossbar network that has same flexibility with HHBN.We integrated the design compiler software at Synopsys company.The results show that compared with the Crossbar network in different width,HHBN reduce the area about 20％ ～ 50％,which reduces the resources consumption of extraction operation for different stream cipher algorithm,so as to improve the efficiency of it.关键词
