摘要
引入了密码安全的一些新度量指标,讨论了这些指标之间的关系。以此为基础得到布尔函数安全准则的新定义,给出非线性度新的上界,说明了这些上界与一般上界之间的关系。
Some new indexes about cryptographic security are introduced, and their relationships are discussed. On the basis of these indexes, several security criteria of Boolean functions are characterized, and the upper bounds of non-linearity and the relationship between these upper bounds and the generic upper bound are showed.
