為了解決沒有第三方認(rèn)證的情況下，P2P 網(wǎng)絡(luò)通信過程中對等點(diǎn)的授權(quán)問題，本文基于P2P 網(wǎng)絡(luò)中對等點(diǎn)的信任度管理，提出了利用P2P 網(wǎng)絡(luò)結(jié)構(gòu)的特點(diǎn)來構(gòu)造一個(gè)多態(tài)性密碼的新方法。該理論提供了可實(shí)現(xiàn)的自編譯的密碼通用模式。多態(tài)性密碼采用一個(gè)偽隨
機(jī)數(shù)產(chǎn)生器，這個(gè)產(chǎn)生器包含許多簡單的偽隨機(jī)數(shù)產(chǎn)生器用于產(chǎn)生一個(gè)混亂的序列，此序列直接和明文位進(jìn)行XOR 運(yùn)算。

Abstract: To solve the problem of authentication for two parties across a communication
channel without the third party, we propose a new method of construction of the Polymorphic
Cipher (PMC) by managing the trust degree of peers in peer-to-peer (P2P) network. The theory
use a pseudo-random number generator which consists of a number of simple pseudo-random
number generators for the generation of a confusion sequence which is directly used to XOR
plaintext sequence.
