面向分组密码算法的高面积效率可重构架构
Reconfigurable architecture with high area efficiency for block cipher algorithms
摘要
Abstract
A coarse-grained reconfigurable architecture is proposed to improve the area efficiency of block cipher algorithms in the security applications.Two schemes are used to optimize the architec-ture.One is using the Benes network to optimize the connection between rows of the reconfigurable architecture,and the other is optimizing the context organization according to the use frequency.The experimental results show that the area cost is reduced by 5 1.6 1% after using the Benes network as the optimization of row connection.After using the hierarchical context organization based on the using frequency,the configuration time of the AES(advanced encryption standard)block cipher al-gorithm and that of the DES(data encryption standard)block cipher algorithm decrease by 80%and 88%,and the proportions of their configuration time in the total time decrease 42% and 39%,re-spectively.The area efficiencies of these two block cipher algorithms implemented on the proposed reconfigurable architecture are 3.95 and 1.5 1 times of the similar architectures,respectively.There-fore,the two proposed schemes can effectively decrease the area cost,improve the performance of the reconfigurable architecture and favor the efficient area implementation of block cipher algorithms.关键词
