目前,适合资源约束的轻量级密码算法已成为研究热点。提出一种低资源、高性能与高安全性的新轻量级分组密码算法Surge。Surge密码分组长度为64位,使用64位、80位和128位3种密钥长度,且基于SPN结构。轮函数分为5个模块,密钥扩展模块采用无扩展方式;轮常数加模块采用0到15的数字组合成轮常数,构造高效且高度混淆的轮常数加变换;列混合模块利用易于硬件实现的(0,1,2,4)组合矩阵,从而可以在有限域GF(2~4)上构造硬件实现友好型矩阵。将Surge算法在FPGA上进行了实现,实验结果表明,相对于目前SPN结构的轻量级密码算法,Surge算法占用的面积资源更小,同时有着良好的加密性能;安全性实验证明了Surge可以有...

Lightweight cryptography algorithm has become a hot research.The paper presented a new lightweight block cipher algorithm named Surge.Surge has low resource,high performance and high security.Block length of Surge cipher is 64 bits.Its variable key uses 64,80 or 128-bit length.Surge is based on the SPN structure.The round function is divided into 5 modules.Key expansion module is no expansion.Round-constants add module uses 0 to 15 to combine so that it can achieve efficient and highly confused round-constrants add operation.MixColumn module uses (0,1,2,4) to composite hardware-friendly matrix...
