摘要

本文讨论了现代流密码中存在的安全问题。正如我们观察到的，有时设计者声称设计的算法更安全，但当它进入公开文献时，我们发现了许多问题。我们讨论雪，尖叫和兔子。人们已经做出了一些努力来克服这些问题，这些问题是由不同的密码分析家指出的。流密码比分组密码更快、更有效，但相对而言安全性较差。本文的重点是在效率和安全性方面做出一些妥协。流密码，块密码，雪，尖叫，兔子，混乱。

Cryptanalytic weaknesses in modern stream ciphers and recommendations for improving their security levels

Inthis paperwediscuiss security problems insom'1e modern stream ciphers. Asweobserve somie tinmes that adesigner claims that thealgorithm designed is mnore secure butt whenitcomestoopenliteratuire we finda numberQfproblems. We discuss SNOW, Scream andRabbit. Someejforts havebeenmadeto overcome theproblems those werepointed outin these cryptosystems bvdifferent cryptanalysts. The stream ciphers arefaster andefficient thanblock ciphers butconmparatively less secure. Ouremphasis inthis paperistomak-e somecompromise on efficiency buttogetnmor-e security. IndexTerms- Streamciphers, Blockciphers, SNOW,Scream, Rabbit, chaotic.
