幂剩余函数具有十分良好的密码式单向特性,因而在近代公开密钥保密通信系统中获得了重要应用。本文系统地讨论了幂剩余函数的基本特性,指出了在密码技术中可能的应用途径和该函数基本特性对某些应用方式所附加的限制条件。
Exponential power function has a very good one-way password characteristics, and thus in modern public key secure communication system has been an important application. This paper systematically discusses the basic properties of the power residue function, and points out the possible applications in the cryptography and the limitations imposed by some basic functions of the function.
