偶数元择多函数的密码学性质
Cryptographic propertis of even variables majority functions
【摘要】 择多函数因为具有最高的代数免疫(AI)而备受密码工作者的关注。证明了偶数元择多(EVM)函数在AI达到最大的同时具有很好的稳定性和抵抗相关攻击的能力,并构造出一类与偶数元择多函数线性等价的相关免疫函数。
【Abstract】 People pay much attention to majority functions because they have optimum Algebraic Immunity (AI).This paper discusses Even Variables Majority (EVM) function.EVM functions have good stability and ability to resist correlation attack.This paper also constructs a kind of correlation immunity Boolean functions which is affine equivalent to EVM functions.
