In rural China, marriage-squeezed men are more likely to experience discrimination than other males. Using data collected from Anhui Province in China on marriage-squeezed men’s quality of life, this ...
Systematical characterization of YUCCA gene family in five cotton species, and potential functions of YUCCA22 gene in drought resistance of cotton
棉花 YUC基因家族 生长素合成
2024/5/17
生长素在植物的正常生长发育中起着至关重要的作用。TAA/YUCCA基因家族编码色氨酸氨基转移酶（tryptophan aminotransferase），是生长素合成的关键酶。然而，棉花中YUCCA（YUC）基因家族尚未见报道。为了揭示YUC基因在棉花中的功能，我们系统地鉴定了五个棉种中的YUC基因家族，包括成员分析、特征描述、基因组内复制和共线关系。转录组学分析表明，GhYUCs参与了棉花的非生...
Coniferous-Broadleaf Mixture Increases Soil Microbial Biomass and Functions Accompanied by Improved Stand Biomass and Litter Production in Subtropical China

Although the advantages of multi-species plantations over single-species plantations have been widely recognized, the mechanisms driving these advantages remain unclear. In this study, we compared sta...
Efficient Range-Trapdoor Functions and Applications: Rate-1 OT and More
Trapdoor functions range trapdoor hash power DDH
2019/9/3
Substantial work on trapdoor functions (TDFs) has led to many powerful notions and applications. However, despite tremendous work and progress, all known constructions have prohibitively large public ...
Linear Approximations of Random Functions and Permutations
random function random permutation multinomial distribution
2019/8/19
The goal of this paper is to investigate the behavior of the ideal cipher under linear cryptanalysis. The motivation of this work is twofold. First, before a practical cipher can be distinguished from...
Count of rotational symmetric bent Boolean functions
Rotational Symmetric Boolean Function Algebraic Normal Form Bent Boolean Function
2019/8/2
Counting the Boolean functions having specific cryptographic features is an interesting problem in combinatorics and cryptography. Count of bent functions for more than eight variables is unexplored. ...
Relation between o-equivalence and EA-equivalence for Niho bent functions
Bent function Boolean function EA-equivalence
2019/7/15
Boolean functions, and bent functions in particular, are considered up to so-called EA-equivalence, which is the most general known equivalence relation preserving bentness of functions. However, for ...
On equivalence between known families of quadratic APN functions
CCZ-equivalence EA-equivalence APN
2019/7/15
We study a question whether the currently known families of quadratic APN polynomials are pairwise different up to CCZ-equivalence. We reduce the list of these families to those CCZ-inequivalent to ea...
Code Constructions for Physical Unclonable Functions and Biometric Secrecy Systems
Information theoretic security key agreement physical unclonable functions
2019/7/8
The two-terminal key agreement problem with biometric or physical identifiers is considered. Two linear code constructions based on Wyner-Ziv coding are developed. The first construction uses random l...
On the Complexity of Collision Resistant Hash Functions: New and Old Black-Box Separations
Collision Resistance Statistical Zero Knowledge Black box separations
2019/6/12
The complexity of collision-resistant hash functions has been long studied in the theory of cryptography. While we often think about them as a Minicrypt primitive, black-box separations demonstrate th...
A Note on the (Im)possibility of Verifiable Delay Functions in the Random Oracle Model
Verifiable Delay Functions Random Oracle Model
2019/6/6
Boneh, Bonneau, B{\"u}nz, and Fisch (CRYPTO 2018) recently introduced the notion of a \emph{verifiable delay function} (VDF). VDFs are functions that take a long \emph{sequential} time TT to compute, ...
A Verifiable Delay Function (VDF) is a function that takes at least TT sequential steps to evaluate and produces a unique output that can be verified efficiently, in time essentially independent of TT...
