摘要
随着信息社会的发展与进步,信息安全问题越来越受到人们的关注。如何确保信息安全,实现信息的保密性,成为了科学研究的一个重点。为实现信息安全,很多方面都会应用到密码,对信息采取防护措施,从而达到保证信息安全性与保密性的目的。本文主要对序列密码的基本概念及密码设计方法进行了简述,着重在对流密码SNOW2.0算法实现与发展分析,并对SNOW2.0算法的GD攻击、线性区分攻击以及代数攻击进行了阐述,希望能够为信息安全领域提供一定的参考价值。
With the development and progress of information society, the problem of information security more and more get the attention of people. How to ensure information security, to achieve the confidentiality of information, has become one of the focuses of research. To realize information security, many ways can be applied to the password, take protective measures to the information, so as to achieve the goal of guarantee the information security and confidentiality. This article mainly discusses the basic concepts of sequence code and password design method on the brief,, focused on analysis of convection password SNOW2.0 algorithm implementation and development, and a lot of GD attack SNOW2.0 algorithm, linear to distinguish between attack and algebraic attack, hoping to provide certain reference value in information security field.
