摘　　要：本文发展了无记忆组合函数相关度的概念。给出了计算公式和方法。论述了与相关免疫的关系。提出了相关度的界及最优攻击函数。展示了利用高阶相关度的破译实例。The correlation measure of combining function without memory is developed. A methed of calculation is given. The relation between correlation measure and correlation immunity is described. Its boundary and the optimal attack functions are derived. Finally, a cryptanalytic example by using high order correlation measure is presented.
