通过对代数次数增加情况的分析，研究了type-1广义Feistel结构下，单SP(substitution-permutation)模型与双SP模型抵抗高阶差分分析的能力。结合高阶积分与高阶差分思想，开发了四路type-1广义Feistel-SP与Feistel-SPSP结构代数次数上界估计的新方法。利用这一方法，分别构造了这2种结构在2种常用参数下的区分器。结果显示，四路type-1广义Feis...
Classification of poset-block spaces admitting MacWilliams-type identity
Classification poset-block spaces admitting MacWilliams-type identity
2012/3/1
In this work we prove that a poset-block space admits a MacWilliams-type identity if and only if the poset is hierarchical and at any level of the poset, all the blocks have the same dimension. When t...
Periodic Solutions and Global Asymptotic Stability of a Delayed Discrete Predator-Prey System with Holling II Type Functional Response
Coincidence degree discrete predator-prey system global asymptotic stability positive periodic solutions
2007/8/7
In this paper, we study the existence and global asymptotic stability of positive periodic solutions of a delayed periodic predator-prey system with Holling II type functional response. By use of the ...
Delay differential systems are widely used in many different fields. It isimportant to determine the local stability of their equilibria. For systems withdelay dependent parameters, the stability anal...
In this paper, such new definitions as $D$-$B$-preinvexity, strictly$D$-$B$-preinvexity and explicitly $D$-$B$-preinvexity for vector-valued mappingsare firstly introduced. Then, a sufficient condit...
ALMOST PERIODIC SOLUTION FOR A CLASS OF LOTKA-VOLTERRA TYPE $N$-SPECIES ECOLOGICAL SYSTEMS WITH TIME DELAY
Infinite delay diffusion uniform persi
2007/8/7
The uniform permanence and global asymptotic stability of aclass of almost periodic Lotka-Volterra type $N$-speciescompetitive systems with diffusion and delays are investigated. Itis shown that the ...
A method for obtaining the explicit pointwise bounds on solutions to the general form of linear systems of Volterra integral inequalities in n independent variables is recomended. All known results re...
ON ASYMPTOTICALLY MEDIAL UNBIASED ESTIMATORS IN TRVNCATED-TYPE DISTRIBUTION FAMILIES
Truncated distribution asymptotically me

In this paper, the author constructs asymptotically medial unbiased estimators for two classes of truncated-type distributions.
A CRYPTOGRAPHIC STUDY ON S—BOXES OF DES TYPE Ⅱ AN ENTROPY LEAKAGE ANALYSIS FOR THE KEY
DES S-box entropy
2007/8/7
The concept of key-entropy drop in an S-box is introduced. It is established that the output functions of the permutations composing an S-box belong to three patterns of key-entropy drop. An analysis ...
A CRYPTOGRAPHIC STUDY ON S—BOXES OF DES TYPE Ⅰ AN INTEGRATED ANALYSIS OF THE DESIGN CRITERIA FOR S-BOXES
DES S-box
2007/8/7
An integrated analysis of the design criteria for the S-boxes used in the DES is made. Among others, the exclusion principle between the degree of nonlinearity and the degree of I/O—correlation immuni...
