內(nèi)容概要

本書主要研究有限自動機(jī)的可逆性理論及其在密碼學(xué)上的應(yīng)用。此外,也討論自治有限自動機(jī)和拉丁陣,它們與有限自動機(jī)單鑰密碼的標(biāo)準(zhǔn)形有關(guān)。    有限自動機(jī)是被認(rèn)為是密碼的自然模型。本書作者提出并發(fā)展了RaRb風(fēng)變換方法,用它徹底解決了有限域上(擬)線性有限自動機(jī)的結(jié)構(gòu)問題。與經(jīng)典的線性系統(tǒng)“傳輸函數(shù)方法”不同,RaRb變換方法可推廣到非線性有限自動機(jī);大量弱可逆有限自動機(jī)及其弱逆可用它產(chǎn)生,這就導(dǎo)致基于有限自動機(jī)的公開鑰密碼(簡記為FAPKC)的提出。    本書可用作計(jì)算機(jī)科學(xué)和數(shù)學(xué)專業(yè)高年級和研究生課程的參考書。

作者簡介

陶仁驥,工作于中國科學(xué)院軟件研究所,中國密碼學(xué)界學(xué)術(shù)帶頭人。1985年,基于有限自動機(jī)可逆性領(lǐng)域的工作,陶仁驥先生和陳世華先生開創(chuàng)性地提出了FAPKC,有限自動機(jī)公開鑰密碼體系。該體系是目前世界上不多的投入實(shí)際使用的公鑰密碼體系之一。該體系在國際上被稱作Tao-Chen體制,在經(jīng)典教科書《應(yīng)用密碼學(xué)》中有所介紹。
