摘要

为了提高分组密码算法的工作效率

提出了一种基于链接与计数(chaining&counter)的快速认证模式(CCTR)

并论证了其安全性。速度测试表明CCTR模式比常用认证模式(例如CBC-MAC)快30%左右。依赖性测试表明:CCTR模式是完备的;其雪崩效应度约为0.9993;其严格雪崩准则度约为0.992。频率测试表明CCTR模式的输出服从均匀分布。二进制矩阵秩、动向(run)、频谱、非重叠字(non-overlapping template)匹配、重叠字匹配、Maurer通用统计、Lempel-Ziv压缩、线性复杂度、系列、近似熵、累积和、随机游程以及随机游程变量等测试结果都满足要求。由此说明

CCTR模式具有很好的伪随机性

这就从统计评估的角度验证了CCTR模式的安全性。

Abstract

For raising the operation efficiency of block cipher algorithms

a fast authentication mode based on chaining ＆ counter（CCTR） was put forward;and its security was proved.Its speed was about 30% faster than that of authentication modes in common use（for example

CBC-MAC）.The dependence test results accord with the demands.The CCTR mode is complete;its degree of avalanche effect is about 0.999 3;its degree of strict avalanche criterion is 0.992 or so.The frequency test results indicate that the output generated by the CCTR mode had uniformity.The binary matrix rank

spectral

non-overlapping template matching

overlapping template matching

Maurer’s universal statistical test

Lempel-Ziv compression

approximate entropy

cumulative sums

random excursions and random excursions variant tests results fulfilled the requirements all.Therefore

the CCTR mode has good pseudo-randomness

which the security of CCTR mode is verified by way of statistical evaluation.
