摘要
讨论了分组密码随机算法的优点和实现问题,并描述了随机算法在CAST和SAFER+中的若干实现,分别称为随机盒、随机网络和随机群。它们以计算复杂度的少量增加换取了安全性的明显提高。
The advantages and implementations are discussed about random algorithms of block ciphers. Some implementations are described about random algorithms in block ciphers CAST and SAFER + , which are called random box, random network and random group respectively. They get implicit strengthening in security by a little increase of calculating amount.
