摘要/Abstract

摘要： 随着信息技术的飞速发展,如何保护信息的安全,使之不被窃取及不至于被篡改或破坏,已成为当今普遍关注的热点问题。为了解决这个热门问题,主要研究了一种新式Vigenere密码的解译算法,其通过确定Vigenere密钥的长度和密钥字以及明文,最终得出该种新式Vigenere密码的破译算法。

关键词: Vigenere密码,Kasiski测试法,重合指数,重合互指数,相对移位

Abstract: With the rapid development of information technology,how to protect the security of the information not stolen and not subject to tampering or destruction,has become a hot issue in present.In order to solve this question,this paper mainly researched the interpreter of a new vigenere password algorithm.We used vigenere to determine the length of the key and the key word and plaintext.Eventually we got the new vigenere password decipher algorithm．

Key words: Vigenere password,Kasiski test method,Coincident index,Coincidence interaction index,Rrelative shift
