差分故障攻击在密码分析中的应用

Differential fault attack on its application in the cryptanalysis

信息时代的到来给世界带来翻天覆地的变化,以密码学为代表的信息技术为信息时代发展提供了理论基础和安全保障。密码学包括密码设计和密码分析两部分,本文介绍了在密码分析中一种重要和热门的方法——差分故障攻击方法。这是一种高效强力的密码攻击方法,来源于差分分析,应用广泛,对几乎所有密码方案都产生巨大威胁。当然,这种方法从提出到应用也经历了很多争议和考验。

the arrival of information age brings to the world of great change, information technology represented by cryptography provides a theoretical basis for development in the information age and security.Cryptography design including passwords and password analysis two parts, this paper introduces the cryptanalysis of an important and popular method, differential fault attack methods.This is a kind of efficient and strong password attack method, is derived fi＇om the difference analysis, wide application, for almost all password scheme to produce a great threat.From the very beginning, of course, this approach to the application also experienced a lot of controversy and test.
