论文提出了一种新的高安全轻量级密码算法,命名为Magpie.Magpie是基于SPN结构,分组长度为64位,密钥长度为96位,包含32轮运算.Magpie密码算法包括两个部分:运算部分和控制部分.运算部分,每轮运算包括五个基本运算模块:常数加,S盒变换,行移位,列混合,轮密钥加.控制部分,将密钥的第65位到96位作为Magpie加密算法的控制信号,其中密钥第65位到第80位作为S盒变换控制信号,第81位到第96位值作为列混合,行移位变换和每轮运算的控制信号.在Xilinx Virtex-5 FPGA上实现面积仅为10679 Slices,加密速率为6.4869Gb/s.

We present,so called,Magpie which is a new high-security lightweight block cipher.The block size of Magpie is 64 bits and the key size is 96 bits.It employs a SPN structure and consists of 32 rounds.Magpie encryption algorithm includes two parts:operation part and control part.Each operational round includes five basic modules:AddConstants,SubCells,ShiftRows,MixColumns,AddRoundKey.The control part is the key of 65 to 96 bits.65 to 80 bits of key control the SubCells.81 to 96 bits of key control the MixColumns and the ShiftRows.The control signal can control the order of the module operation.Th...
