摘要

NTRU公钥密码体制的陷门单向函数与以往的有所不同

其单向性依赖于会话密钥的随机性

且解密不需要知道有关随机会话密钥的任何信息.有人把它称为概率陷门单向函数

但不能完全体现特殊性.为此提出了具有辅助随机变量的陷门单向函数这一概念

用它可以统一概率公钥加密的陷门单向函数模型.最后将该定义推广到了多元的情况

并讨论了可能的用途.

Abstract

The trapdoor one-way function in NTRU is different from previous ones.Its one-wayness depends on the randomness of session keys

and decryption needs not any information about the session key.Someone called this kind of functions as "probabilistic" trapdoor one-way function.We believe this cannot show all the particularities.So we proposed a new notion

i.e.trapdoor one-way function with an auxiliary random variable

by which we can also unify the trapdoor one-way function model of probabilistic public key encryptions.The concept has been extended to the situation of higher dimension

and possible use has been discussed finally.
