Qu-Tan-Tan-Li函数、Zha-Hu-Sun函数和Tang-Carlet-Tang函数是近些年提出的差分均匀度为4、各项安全性指标均优良的向量值密码函数。研究与这3种密码函数仿射等价函数的计数问题。利用有限域的一些性质,分别计算出与Zha-Hu-Sun函数仿射等价函数数量的上下界,与Qu-Tan-Tan-Li函数和Tang-Carlet-Tang函数仿射等价函数数量的上界。此外,对于Zha-Hu-Sun函数仿射等价函数数量的精确值提出了猜测。研究结果表明,有限域GF(2~8)上至少有2^(53)[8∏i-1(2i-1)]~2个与Zha-Hu-Sun函数仿射等价的密码函数可直接用于分组密码的S盒。

The burgeoning market for lithium-ion batteries has stimulated a growing need for more reliable battery performance monitoring. Accurate state-of-health(SOH) estimation is critical for ensuring battery operational performance. Despite numerous data-driven methods reported in existing research for battery SOH estimation, these methods often exhibit inconsistent performance across different application scenarios. To address this issue and overcome the performance limitations of individual data-driven models,integrating multiple models for SOH estimation has received considerable attention. Ensemble learning(EL) typically leverages the strengths of multiple base models to achieve more robust and accurate outputs. However, the lack of a clear review of current research hinders the further development of ensemble methods in SOH estimation. Therefore, this paper comprehensively reviews multi-model ensemble learning methods for battery SOH estimation. First, existing ensemble methods are systematically categorized into 6 classes based on their combination strategies. Different realizations and underlying connections are meticulously analyzed for each category of EL methods, highlighting distinctions, innovations, and typical applications. Subsequently, these ensemble methods are comprehensively compared in terms of base models, combination strategies, and publication trends. Evaluations across 6 dimensions underscore the outstanding performance of stacking-based ensemble methods. Following this, these ensemble methods are further inspected from the perspectives of weighted ensemble and diversity, aiming to inspire potential approaches for enhancing ensemble performance. Moreover, addressing challenges such as base model selection, measuring model robustness and uncertainty, and interpretability of ensemble models in practical applications is emphasized. Finally, future research prospects are outlined, specifically noting that deep learning ensemble is poised to advance ens

分组密码的安全性主要依赖于S盒(向量值密码函数)的各项安全性指标.分组密码S盒的最优选择就是差分均匀度为4的向量值密码函数.逆函数是最著名的差分均匀度为4各项安全性指标均优良的向量值函数.著名的AES分组密码算法、Camellia分组密码算法、CLEFIA分组密码算法和SMS4分组密码算法均采用有限域F28上与逆函数仿射等价的向量值函数作为S盒.目前对于与逆函数仿射等价S盒的研究,主要侧重于研究分组密码算法经过多轮后活跃S盒的数量.与以往的研究角度有所不同,该文要研究有限域F_(p^n)上与逆函数仿射等价向量值密码函数的计数问题.若能计算出与逆函数仿射等价密码函数的数量,在实际应用中就知道有多少个与逆函数仿射等价的S盒可供算法设计者选择.将有限域F_(2~n)上的逆函数推广成有限域F_(p^n)上的逆函数,其中p≥2是一个素数,这是一个更为一般的逆函数.首先,该文定义(T_1,R_1)和(T2,R_2)之间的运算"*"为(T2,R_2)*(T_1,R_1)··=■,其中(T_1,R_1),(T2,R_2)∈Aff_n^(-1)(F_q)×Aff_n^(-1)(F_q),Aff_n^(-1)(F_q)是有限域F_q上的n×n阶可逆仿射变换群,q=p^m,p≥2是一个素数,m≥1是一个正整数,"■"表示映射的合成.证明了Aff_n^(-1)(F_q)×Aff_n^(-1)(F_q)关于运算"*"是一个群;使得等式F=■成立的可逆仿射变换对(V,W)∈Aff_n^(-1)(F_q)×Aff_n^(-1)(F_q)关于运算"*"是Aff_n^(-1)(F_q)×Aff_n^(-1)(F_q)的一个子群.然后,利用以上结论和有限域的一些性质证明了,当p≥3且n≥2时,或者p=2且n≥4时,对于有限域F_(p^n)上的逆函数F(x)=x^(-1)=x^(p^n-2),使得等式F=■成立的可逆仿射变换μ和ν线性化多项式的形式只能是μ(x)=S_tx^(p^t)和ν(x)=S_t^(p^n-t) x^(p^n-t),0≠St∈F_(p^n),t=0,1,…,n-1.于是,使得等式F=■成立的所有可逆仿射变换对(ν,μ)的数量为n(p^n-1).利用这些可逆仿射变换对(ν,μ)所形成的子群对群Aff_n^(-1)(Fp)×Aff_n^(-1)(Fp)划分等价类,商集中陪集首的个数即为与逆函数仿射等价密码函数的数量.因此,在这种情况下,与逆函数仿射等价密码函数的数量为■.最后,当p=2且n=3时,对于有限域F_2~3上的逆函数F(x)=x^(-1)=x^(2^3-2),利用计算机作为辅助手段测试出使得等式F=■成立的可逆仿射变换对(ν,μ)的数量为168.利用这些可逆仿射变换对(ν,μ)所形成的子群对群Aff_3^(-1)(F2)×Aff_3^(-1)(F2)划分等价类,商集中陪集首的个数即为与逆函数仿射等价密码函数的数量.因此,在这种情况下,与逆函数仿射等价密码函数的数量为10 752.研究结果表明,在实际应用中,有限域F2~8上有■个与逆函数仿射等价的密码函数可作为分组密码的S盒使用.
