【摘要】 本文把序贯概率比检验引入到密码分析中,用来约减相关攻击所需的密钥量。在对蓝牙生成器的相关攻击中,采用序贯概率比检验可把所需密钥量约减到原来的36.6%。更多还原

【Abstract】 In this paper, the Sequential Probability Ratio Test (SPRT) is introduced to cryptanalysis to reduce the amount of keys needed in correlation attacks. In the correlation attack to "Bluetooth Generator", the keys needed with SPRT are only 36.6 percent of that with traditional methods.更多还原
