摘要
文章介绍了RC4流密码体制,详细解释了RC4密钥流区分器的含义,描述了基于第二字节偏差的密钥流区分器,并在软件上实现了该区分器。实验结果表明,如果设定区分器的大小N=28=256,那么一次区分成功的可能性大约为59%。文章最后指出该密钥流区分器在攻击广播RC4加密中的一个应用。
Stream cipher RC4 is introduced and RC4 key stream distinguisher is elaborated. A distinguisher based on second byte bias is depicted and implemented by software. It shows that the probability of one time distinguishing successfully is about 0.59, when the size of the distinguisher is N=2^8=256. The application of the distinguisher in attacking broadcast RCA is presented,
